How Do I Know What Brushless Motor Is Best?

Motors are designed with Speed and Torque in mind at a given voltage and current (amps consumed) level. Torque is the ability of the motor to move the load. The best motor is the one in there right now most likely. Pull that one out and find who makes it and get the specifications. Then you can shop for better specs if you want, but increasing torque or speed may create the need to beef up the rest of the drive train to handle it or you can twist the drive shaft or strip gears. Good luck

1. Brushless motor driver fails at PWM duty > 10%

Ok to sum it up:Calculation of Bootstrap Capacitors: Datasheet states that the voltage drop on the bootstrap cap shall not be more than 400mV; Total Gate Charge of MOSFET is approximately 60nC considering your Gate to Source voltage. The minimum required bootstrap cap is therefore CBoot_min = 60nC/400mV --> 150nF --> use 220nFAdjust Gate resistances: High Gate resistance results in long transitions times of the FETS which has a positive effect considering EMI but a negative effect on power loss of the FET (long VDS/ID overlap), also you waste a long time switching (appr. 1us with your config). Considering the deadtime of 1.4us you might even have crossconduction. I suggest you go with a gate resistor below 10 Ohm. Hot high side fets: Probably a combination of long transition times (possible crossconduction) and the probably lower VGS voltage of the high side fets

2. Where can I find 90 VDC 25 HP Brushless Motor for Electric car?

No thanks! I will keep my 2009 Toyota 4Runner Limited 4.7 V8 4WD and my 2007 Toyota Tacoma crew cab 4X4......I do not buy Garbage Motors ( GM ) made in Mexico with Chinese parts. .......Toyota and Honda already have "green cars" the Prius and the Insight.....until GM improves the quality and lowers the price below the imports I will not even look......why would I pay the same price or more for a car of less quality? Until the BIG3 stop taking Americans for granted the slide will continue regardless of government bailouts.

3. How fast will a Traxxas E-Maxx go with a HV6.5 High-Voltage Sensored Brushless Motor?

It is alot faster. The 6.5 is almost a third faster and more easy to use

4. Can I power a brushless motor with 12V DC adapter instead of using a LiPo battery?

Obviously you can but in that case it will be just indoor activity. LiPo are used in portable application. Whatever power source you may use, it must be of high power and noise free,pure DC supply with no ripples. After all you need to generate 3phase AC signal to drive your bldc. Can I power a brushless motor with 12V DC adapter instead of using a LiPo battery?

5. ESC Output Current for a Brushless Motor with a Given Max Current Rating

With 6 step commutation each phase wire is connected for 2 out of every 3 steps, so as a rough guide you can assume that it conducts 2/3 of the average motor current. That means you can generally get away with motor wires that are one gauge smaller than the battery wires. Getting a more exact figure is harder because the current waveform varies depending on motor characteristics and throttle level. Below is an example scope trace of current in one phase wire of a brushless model aircraft motor. In this case the battery current was measured at 15.4A. We see that current is flowing for 2 out of every 3 steps, and the current during this time is fairly flat at 16A. Therefore the average current over a full cycle should be 11A and the rms current should be 13A. And here's the same motor running at part throttle on a higher voltage battery, showing the effect of PWM:- In this case the battery current was only 10.3A, but the waveform has become triangular and peaks at 32A. The average and rms currents are still 11A and 13A, but are now higher than the battery current

6. Is installing a brushless motor into a 2WD Traxxas Slash really worth it?

It all depends. I have the 2WD slash and I do not race. I bought the VXL brushless system for mine and holy crap....it's more than just a 5mph jump. It's crazy fast, especially when you add a 2S or 3S lipo to it. If you are just bashing in the back yard it would be fun to have, and would smoke whatever your friends are running. However, if you do decide to race you would have to race the modified class if one is available. Most SC races that I know of are stock, with brushed motors. The VXL (if that's what you were thinking about getting) or pretty much any brushless set up is going to be a bit harder to control/handle since the slash is only 2WD. It takes some practice and getting use to but you will get better with it. They are easy to maintain and last a lot longer than brushed motors. I love the VXL and it was worth switching over to brushless for me. I enjoy the crazy speed. If you look on eBay you will spend far less than $160 for a new set up. Still around $100 and closer to $125. And just a helpful hint, do not run it on grass. Brushed or brushless. The strain on the motors will cause them to overheat and ruin them. Try to stay on dirt or road. Grass is bad for Nitro AND electric RC motors

How to You Hook Up a Brushless Motor with All of the Parts to a Battery to Make a Model Plane Fly?
I HOPE you do NOT mean solid wood!! power wiring for motor = motor to electronic speed controller to batteries. control wiring = batteries to receiver to electronic speed control, rudder servo, elevator servo, etc. control from servos to control surfaces usually push rods or cables.1. Need a Brushless motor for a R/C boat?Your eBay motor could certainly be put in a boat, and it would not need a gearbox, but there are a lot of questions still. Will the boat take the weight? You are going to need 50-100 amps from the battery for the two highest-revving versions - that's going to be 300-500 grams of expensive lithium battery for about 5 minutes running. Then you are going to need very high quality bearings on both ends of the prop shaft to run at those sorts of speeds. At your stage i would recommend getting some expert advice from your model shop. Yes, the bits might cost more, but the advice is priceless and you might save your boat catching fire.2. What reasonably priced ESC from hobbyking would you recommand for this brushless motor?Dude, just go on there website and look3. what is the advantage between an inrunner and outrunner brushless motor in a model aircraft?Inrunner Vs Outrunner: An inrunner motor has stationary coils which surround the rotating magnet at the center. An outrunner motor has stationary coils at the center, and the rotating magnet on the outside. Outrunner motors generally have lower Kv ratings, meaning they run at a lower speed, but with more torque, which would allow you to direct drive larger props without needing a gearbox. Most RC cars and boats would require an inrunner brushless motor.4. How are current and voltage related to torque and speed of a brushless motor?Voltage and current are the essential components of power a.k.a. the ability to perform work. To do work by means of spinning machinery requires a rotary-acting force - a torque. The rate at which the work proceeds (introduce time) and the measurement becomes of power. More power - increase either current or voltage or both5. A2212-15t 930kv brushless motor voltage limitSpeed is proportional to voltage. The kv is 930 RPM per volt. With the 11.1 volts maximum recommended voltage the no-load speed is 10320 RPM. With your proposed 18.5 volts, the no-load speed will be 17,200 RPM until something fails6. will blocking the output of a dc 12 volt brushless motor hurt it or make it get hot and burn up?possibly, depends on where the block is, how big the ducts are, lots of unknowns. Best to monitor the speed of the motor. If it slows down a lot, then it could overheat.7. heading lock gyro and brushless motor for rc heli question.?A heading lock gyro will will keep your heli pointed in a certain direction or heading by controlling the pitch of your tail rotor ( I will leave a link for a you tube video which will put a visual to my words) and brushless motors to put it simply longer flight times and less maintenance more money8. Confusion with winding voltages for a fixed positioned brushless motorIt depends on the driver. Sometimes the driver provides a holding current that is lower than the drive current, to help ensure the motor does not move when you do not want it to.Yes, the 6 step type is limited to 6 steps. It can not create more than that because this is saying the driver is only capable of supplying 6 different voltages. More goes into it than that, but that is the simple version9. How fast does an electric, brushless motor driftstar rc car go?An electric, brushless motor driftstar rc car goes about 45 miles per hour10. How does a DC brushless motor work?To state it simply, a DC brushless motor is not a DC motor. It is an AC motor with an inverter (or electronic commutator) on the front end to make the AC, so you can use a DC input.11. Can a DC brushless motor produce the same torque at different power levels?A stall, the motor speed is 0 and so the power. This is the point that you are mentioning. The datasheet further mentions, the max power which is the middle speed position. The nominal output is somewhere near max efficiency output. You may also see that at stall the efficiency is zero, meaning all the electrical input power is converter into a loss- heat.EDIT:I see, what is is bugging you. The graph presents 12V DC link voltage, well that's not a motor voltage. It's the input voltage of the driver, which outputs the setpoint current, the voltage simply is $V=Icdot R$ and not the DC link voltage, the driver does PWM
Brushed Motor V Brushless Motors
If you are new to the world of radio control, or are just out of touch with the new technology, you may not know the differences between conventional brushed and brushless motor systems. I have written this guide to help other radio control enthusiasts understand the differences between the two. Brushless motors offer more power and higher efficiency than the equivalent brushed motor of the same size. You will get longer run times and higher speeds with a brushless motor of the same physical size, and very little maintenance is required with the brushless type. The internal workings of both brushed DC (direct current) and brushless DC motors are based on the same idea; the motor windings have current supplied to them and an electromagnetic field is generated, which pushes/repels against the permanent magnets and causes the shaft to turn. As the shaft turns, this pushing energy transfers from one set of windings to the next causing the motor shaft to rotate continuously. The differences between the two motor types are listed below, as well as the advantages and disadvantages. With a brushed motor, the windings are fixed onto the central shaft inside the motor case and spin with the shaft when current is applied. The permanent magnets do not move - they are fixed to the inside of the motor can. Power is supplied to the motor windings by two brushes (positive and negative) that push against the commutator on the central shaft. The friction between the brushes and the commutator is the reason why this motor is not as efficient as a brushless motor. Also, the brushes and commutator will wear out after some time, so brushed motors require maintenance and replacement parts from time to time. A more powerful brushed motor will wear out quicker than a slower one. If you have ever owned a ready-to-run electric rc car, chances are that you would have used a brushed rc motor at some point. Due to their affordability, brushed motors are usually supplied with most entry-level to mid-range radio control car kits. The extremely popular Tamiya kits, for example, are usually supplied with a standard 540 type silver can. The brushed DC motor goes back to the mid 1800's and it was this type of motor that first appeared in the early radio controlled car kits. Simple wiring - brushed motors only require two wires to power them and do not require any electronic commutation. Therefore, brushed Electronic Speed Controllers (ESC) are relatively inexpensive. Brushes and commutator wear out after time, although they are rebuildable in some motors. Not very efficient when compared to brushless. More power is wasted through the additional heat loss and friction of the brushes against the commutator. This means you will have shorter run times. The brushless motor does not require a physical commutator; this is one of the reasons they are so popular today. No commutator or brushes means almost zero maintenance (the bearings will last a very long time but obviously not forever). You will find a brushless motor system in the more expensive ready-to-run cars, and most serious racers will use this type of motor, if permitted. Brushless motor technology was invented in the 1960's but did not really become available for radio controlled cars until around 2003-2004 (earlier for model aircraft). None Very low maintenance; no brushes or commutator to wear out. None Higher efficiency compared to brushed so you will get longer run times. A more complicated 'Brushless ESC' is required to power it.1. gas or electric motor?In my opinion? It will be long after this generations dead before everything goes electric. We realize the limited availability of petroleum, but since it still exists, society will keep using it2. Car Window Motor?You can (carefully) use jumper wires off the battery to manually actuate the window motor. Reversing the polarity of the wires will reverse the direction. If the motor works, find a wiring diagram (auto zone can supply you with one) and test the switch with a volt meter. I like to use sewing T-pins to "backprobe" the wires by inserting them into the back of the plug and attaching the voltmeter leads to the t-pins. Doing this allows you to observe the circuit operation without disrupting it, and without damaging the insulation on any of the wires. My money is on the motor though3. what does a pool pump motor sound like?do you have a sump pump in your basement. when its running mid cycle before it starts cavitating. it sounds like any other electric motor with the faint sound of water traveling through a pipe
How to Use LiPo to Power 3 Servos, Brushless Motor, and an Arduino Board
Theoretically, your battery can discharge at up to 55 A (2.2 x 25). So it can provide enough power for all of the devices you listed. But you will need step-down(buck) converters to decrease your voltage level down to operating voltages of servo motors.1. How does a DC brushless motor work?To state it simply, a DC brushless motor is not a DC motor. It is an AC motor with an inverter (or electronic commutator) on the front end to make the AC, so you can use a DC input.2. in a brushless motor, is the more Kv beter or worse?Its better. Basically means more RPM per volt. You need to compare motors that are the same size if your going to see which motor makes more power. In boating, I think your propeller would make the bigger difference in what motor you choose. Also depends on how many volts your running, type of batteries, and the capacity of the batteries.3. 3 phase brushless motor control?The link gives a good introduction to BLDC motors. Good luck with your studies.4. How are current and voltage related to torque and speed of a brushless motor?After 4 years using and studying electrical vehicles I figured out that "gradeability" (ability to raise a slope of specific grade) depends on motor torque, and torque depends on current.Voltage instead "regulates" how fast a motor can run: the maximum speed a motor can reach is the speed at which the motor generates a voltage (named "Counter-electromotive force") which is equal to the voltage it receives from battery (disregarding power losses and frictions for simplicity).How much current a motor can tolerate when a voltage is applied depends on how much thick the coils wires are (thicker = higher current = higher torque), due to coils internal resistance (the higher the resistance, the higher the heat produced, till wires melt). Considering a 1000W motor:The maximum current a motor can tolerate is named "rated current", which is way lower than the motor "stall current", i.e. the current flowing in the motor wires when voltage is applied and the motor is kept halted. The motor CANNOT tolerate its own stall current, which will soon melt wires. That's why electronics limits maximum current to rated current value5. How do you wind a brushless motor for a specific voltage? Is there a formula? Could I get an example?I would strongly advise you not to try winding motors now. Before getting into that business you should thoroughly study the subject and work for a while as an apprentice at a company which winds or rewinds electric motors. After working for them for a few years, then try starting your own business if you still want to. Simply reading posts on quora will never qualify you to be a motor winder6. Pi4J ESC brushless motor is not running stableRaspberry Pi should be relatively bad for this task, because raspbian is not a real-time operating system. See this thread, hope it is helpful: Is it possible to run real time software?7. If cooling is provided, will overvoltage wear out the life expectancy of a brushless motor?The motor suffers from wear at the bearings and breakdown of the windings. So Overvoltage will shorten the life of the windings but cooling will help mitigate that. Bearings will wear depending on maintenance and hours run.8. how to you hook up a brushless motor with all of the parts to a battery to make a model plane fly?I HOPE you do NOT mean solid wood!! power wiring for motor = motor to electronic speed controller to batteries. control wiring = batteries to receiver to electronic speed control, rudder servo, elevator servo, etc. control from servos to control surfaces usually push rods or cables.9. In RCs toys what are the advantages of having a brushless motor vs a brushed motor besides increased speed?Brushed motors have moving parts (magnets) that wear out over time, they also use a different power source. Brushless motors are pretty much maintenance free and are used with lithium powered systems. Lithium is the best battery power source available today. Lithium batteries do have their setbacks. Charging them too long can result in fire and if you run them down too far before charging they will ruin. As long as the person you are buying this for is going to pay attention to this it's okay. If this is a Kid you might want to stick with brushes and Ni-con Batteries. If it's a plane i suggest gas powered and make sure you choose a beginner plane...IE BOX FLY 40. on Cars the gas powered ones are very cool as well, just make sure whoever your getting this for is responsible and has some knowledge of mechanics. Sorry I will answer your question now Brushed motors are a bit more to deal with but nothing like the unreliability of the lithium batteries. The lithium batteries will produce more power for longer with a shorter charge time and they do not slow down at the end of a charge. they run 100% then they stop. Again the lithium batteries are a pain to care for and if you make a mistake, it will cost you money and possibly pain.
Where Can I Buy a Brushless Motor for Building RC Aircraft in India?
RcBazaar, The Coolest hobby super storeRadio Control Planes, Drones, Cars, FPV, Quadcopters and more - HobbykingOnline Shopping for Cool Gadgets, RC Quadcopter, 3D Printer at BanggoodThese are few recommendations for buying online. Some big cities also have shops which sell them, need to find. Above listed sites have almost all products to build a RC Airplane.Hope this helps ^_^Where can I buy a brushless motor for building RC aircraft in India?1. How fast can a 36v 250W DC brushless motor go? Are there any calculations and equations?You stated the most fundamental number in your question: 250 wattsMechanical power is tau * omega, torque times speed.So if your motor were 100% efficient, it can turn at any speed such that the product of torque and speed is 250 W. In reality its efficiency is 2. Will it work if I place hall sensor heads facing magnets in outrunner brushless motorNo that will not work. You must sense flux reversal on 3 consecutive windings only and be precisely positioned so starting torque is always positive, otherwise dither or dead spots (stall) will occur.example3. 3 phase brushless motor control?The link gives a good introduction to BLDC motors. Good luck with your studies.4. Changing push-pull transistors in brushless motor driverI have heard many people working in repair shops that they prefer to change the whole set of transistors or to change some transistors even if they work well because they claim that even working transistors could have got deteriorated due to the burned transistor.Yes, often the other FETs have been stressed and may be partially damaged. In particular, if one FET fails to a short (as they usually do) the FET(s) in the other leg of that phase (SW6 in your case) will have been driving into a dead short. Replacing both FETS - even when the other one appears to be OK - is a good policy.Should I change only the burned transistor or not?Take the risk, or play it safe and do the lot? That's up to you to decide. When repairing a brushless controller I first examine all the FETS for physical signs of damage (burned or cracked case, stuff oozing out the ends etc.) and test each one for shorts or low resistance between Gate/Source/Drain. Then I remove the ones I suspect are faulty, put in just enough new FETs to get the controller working, and test it on a current-limited power supply with a low power motor. If it passes that test then I install the rest of the new FETs (if there were several in parallel) and test it again with full load.In my experience, if more than one phase has a blown FET it is best to replace the lot. However sometimes even that does not work because the controller has some other issue, and then it is not worth the time and effort to repair. Or to make sure that all the new transistors have the same characteristics so they will open and close simultaneously to get the right control signals for the motor.Yes, unless you are sure that any differences are benign you should only use FETs with the same characteristics. In particular, Gate threshold, recommended drive voltage, and total Gate charge (QG) should be similar, to ensure that the new FETs turn on and off at the same speed. If several FETs are paralleled then they should also have similar on-resistance at the applied Gate drive voltage, to ensure that they share the current equally. Of course Gate/Source and Drain/Source voltage ratings must also be the same or higher. However higher voltage parts often have other differences that make them unsuitable.If I should change the other transistors as well, can I change only SW2 and SW4 since those are the ones that complete the circuit with SW5 and the motor coil?No. If SW2 and SW4 are faulty then they will have stressed SW1 and SW2 as well. However the motor coil (unless also shorted) should provide some protection for FETs in other phases. It's worse for FETs in the same phase because there is nothing to prevent a massive 'shoot-through' current when one FET shorts. Is there anything else that I should pay attention to so I can guarantee that the customer does not get back to me with another fault?Make sure the controller can drive a full load with expected power and rpm for a prolonged period, with smooth speed control and no FETs getting hotter than others. A controller with weak FETs may appear to work OK at light load, but run rough or at lower rpm under full load.
Any Advice for Wiring a Brushless Motor to a Potentiometer Or Some Type of Speed Regulator?
Your description sounds correct to me. The parts are not all that expensive, while there are ways that would be cheaper in purchased parts, if you put any value on your time they would probably be more expensive. the control part (but not the ESC) could be done with a PIC microcontroler costing less than a dollar, but it would have to be programed and wired (involving some additional expense for additional components) so the driver you found would probably be the most practical option1. (edit) Brushless Motor - Why does the stator burn up if the rotor doesn't rotate?This answer was given prior to the op changing the question. Originally, the question referred to the motor as being a squirrel cage type. Subsequently, after several comments, the op changed it to a brushless motor. You just can not get the staff any more!When you stall a 3 phase motor it becomes a transformer and, because the rotor is the secondary AND is shorted out (by necessity for it to operate as a motor), you end up with a shorted transformer.Ask yourself why a transformer burns when the secondary is shorted2. Brushless motor specs to maximize stall torqueTrying to guess stall torque from other parameters is not a good idea. Good specifications will tell you the stall torque at some fixed current. There are too many tradeoffs in motor design that you can not reasonably infer this parameter from other single operating point parameters.3. Brushless motor driver fails at PWM duty > 10%What / whoever told you you should use a huge low Zc(f) electrolytic cap across a /-5 PWM with 1 milliohm RdsOn and cap 1 Ohm ESR (est.)Ic= C dV/dt will be huge.This is an AC short circuit condition for a 3 phase DC bridge driver, limited by ESR of the Caps. Remove these and use twisted pairs to motor directly for each phase. Shielded cables and ferrite balun also help reduce EMI. Put 3 low ESR e-Caps across the "VBB-LSS" DC supplyreturn rails very close to each (3) MOSFET pair instead. Use only low ESR caps 110uF with 10m20m Ohm ESR ( similar ESR to RdsOn of FETs, although best designs will use C values similar to uH value of motor coil for low inductance, low DCR motors.4. How to calculate Thrust from a Brushless motor?The motor needs a "fan" to produce thrust5. What do the commutation waveforms look like for a brushless motor?There is a fair deal of literature on the implementation of brushless motor control but here is an overview.To understand the differences between commutation waveforms it is important to understand how brushless motors operate.A three phase (two pole) motor will have three coils around a single magnet in the center. The goal is to energize the coils in sequence so that the shaft of the motor (and its magnet) rotates.There are two magnetic fields that are important here, the field of the rotor (rotating magnet) and the field of the stator (static coils):We refer to the direction of the magnetic field as its "flux vector" because it sounds super cool. The most important thing to learn from this image is that you want the two magnetic fields to be at right angles to each other. This maximizes efficiency and torque. The dumbest commutation scheme is trapezoidal. Using either hall sensors or back EMF from the motor, it is possible to determine if the motor is in one of a discrete number of positions and perform on/off control on one or two coils to lead the magnetic field around the motor:Because there might only be six separate orientations for the stator field, the flux vector of the motor could be anywhere from 60-120 degrees (instead of the desired 90) and therefore you get torque ripple and poor efficiency.An obvious solution here is to switch to sinusoidal commutation and just smooth out the waveform:If you know the exact orientation of the rotor you can just do some trig to calculate the exact PWM duty cycle to apply to each coil in order to keep the flux vector at 90 degrees and bam you have a beautiful 90 degree flux vector. (The rotor orientation can be determined via encoder, interpolation or more advanced estimation such as a kalman filter).So right now you might be wondering how you can do better than sinusoidal commutation. The key flaw of sinusoidal commutation is that the outputs are sent straight to PWM. Because of coil inductance, the current (and therefore flux vector) will lag behind the commanded values and as the motor approaches its top speed the flux vector will be at 80 or 70 degrees instead of 90.This is why sinusoidal commutation has poor high speed performance.This finally brings us to flux-vector control which is a name given to (often proprietary) control algorithms that attempt to ensure the magnetic flux stays at 90 degrees even at high speeds. The simplest way to do this would be to lead the field by, for example, 90-120 degrees depending on how fast you are going, knowing that the actual magnetic flux will lag.More robust solutions involve PID/feedforward to accurately control the current going through each phase. Every servo manufacturer has their own in-house algorithm so I am sure there is some pretty complicated stuff at the bleeding edge. To put it in simplest terms, flux vector control is sinusoidal control of the current going to each phase (instead of just the PWM duty cycle).The line between sinusoidal/flux vector is pretty vague since some companies perform advanced control on their "sinusoidal" drives (which essentially makes them flux vector). Also, since you can technically call almost anything flux vector control the quality of implementations can vary.
Can a Brushless Motor Have a Higher RPM Using the Same Power Input?
A brushless motor is usually of the induction type for AC voltages. This kind of motor operates synchronously. This means that the rpms are primarily determined by the line frequency and not the line voltage. This suggest that the RPMs will not change with the same power input. Of course, if a heavy load is removed, the RPMs will increase slightly but never exceeding the synchronous speed1. what is the advantage between an inrunner and outrunner brushless motor in a model aircraft?Outrunner Vs Inrunner2. what is the principle of brushless motor,how it works?A conventional DC electric motor has a fixed magnet and a rotating wire armature. Power is fed to the rotating armature (a series of wire coils) via brushes and a commutator. The purpose of the commutator is to switch power with the correct polarity to the correct windings to make the armature rotate. In the brushless DC motor, the armature is replaced by a rotating fixed magnet and the fixed magnet replaced by a series of windings or coils. Current of the correct polarity to cause the armature to rotate is fed to the correct windings (coils) using solid state switches and a position sensor. All brushes are eliminated and the electronics allows for accurate positional and speed control.3. How fast does an electric, brushless motor driftstar rc car go?An electric, brushless motor driftstar rc car goes about 45 miles per hour4. Is installing a brushless motor into a 2WD Traxxas Slash really worth it?It all depends. I have the 2WD slash and I do not race. I bought the VXL brushless system for mine and holy crap....it's more than just a 5mph jump. It's crazy fast, especially when you add a 2S or 3S lipo to it. If you are just bashing in the back yard it would be fun to have, and would smoke whatever your friends are running. However, if you do decide to race you would have to race the modified class if one is available. Most SC races that I know of are stock, with brushed motors. The VXL (if that's what you were thinking about getting) or pretty much any brushless set up is going to be a bit harder to control/handle since the slash is only 2WD. It takes some practice and getting use to but you will get better with it. They are easy to maintain and last a lot longer than brushed motors. I love the VXL and it was worth switching over to brushless for me. I enjoy the crazy speed. If you look on eBay you will spend far less than $160 for a new set up. Still around $100 and closer to $125. And just a helpful hint, do not run it on grass. Brushed or brushless. The strain on the motors will cause them to overheat and ruin them. Try to stay on dirt or road. Grass is bad for Nitro AND electric RC motors5. Can i run an electric brushless motor submerged under water?It would also need waterproofing6. Can I power a brushless motor with 12V DC adapter instead of using a LiPo battery?Obviously you can but in that case it will be just indoor activity. LiPo are used in portable application. Whatever power source you may use, it must be of high power and noise free,pure DC supply with no ripples. After all you need to generate 3phase AC signal to drive your bldc. Can I power a brushless motor with 12V DC adapter instead of using a LiPo battery?7. Replacing brushless motor (starting) capacitor with one of a higher capacitanceThe answer is:8. Is the output voltage from a brushless motor AC or DC?Motors do not output voltage, but rather mechanical power. You apparently mean: "Is the output voltage from a brushless motor **controller** AC or DC? I also assume "ESC" means Electronic Speed Control. Brushless motors are indeed typically called "DC Brushless Motors" because they *run* from DC, not AC. All motors must have multiple poles or windings and the field must some how switch from winding to winding so as to cause a rotating magnetic field that "pulls" the rotor around. This switching process is called "commutation". DC brushless motors are most commonly three phase which means there are three windings. The current is switched in these windings in the very common three phase sequence and current does go in both directions. There are indeed AC signals in the windings. PWM or Switching techniques are used to actually control the amount of current and therefore torque to achieve speed control. The small muffin fans actually use a two phase system similar to shaded pole motors, or even a one phase "pulse-like" system and rely on the motor stopping in a certain position so it gets a push from the single pole and coasts until it gets around again. Sooo... DC Brushless motors do indeed run on AC... or DC as you wish too look at it.
Can I Use a Traxxas TQ Radio System with a Traxxas Brushless Motor and Esc?
Yup! that's an exceptionally customary improve, and the majority locate all in one kit kit on Ebay! I even have viewed it some situations, while you are fortunate you will locate it which contain even the lipo batteries!1. what is the principle of brushless motor,how it works?Do a Google search for "step motor". A motor with noisy brushes is a Universal motor that the brushes hit the coil and causes noise. A Step motor is brushless and more quiet and rotates in steps.2. A good place to buy cheap brushless motor for 1/10 scale rc car?evidently like a famous version of the vitara and that that they had an exceptionally undesirable popularity for tipping. beautiful little lady motor vehicle, (does it are available a delicate precise?) its no longer my form of outrage yet i might supply it 5 out of 10!3. what is permanent magnetic brushless motor ?i could even have pronounced "no such element", yet have found out i do not be attentive to each little thing, or perhaps what i presumed I knew (thank you, Google) it type of feels the rotor of a DC 3-section motor includes everlasting magnets mutually as the rotor of an AC motor includes windings, a minimum of for the examples i found4. How do you wind a brushless motor for a specific voltage? Is there a formula? Could I get an example?How do you wind a brushless motor for a specific voltage? Is there a formula? Could I get an example?There are a few factors in BLDC voltage ratings: speed constant, dielectric withstand, and stall current.Dielectric withstand is the easiest - the wire enamel needs to be thick enough to not arc. This can be found on the wire's datasheet. Exceeding this value can pop the insulation and short the coils.Stall current is equal to the applied voltage divided by the winding resistance. Use the wire's "chassis wiring" spec to find the allowable amperage in this case. Exceeding this value can overheat and melt the motor.The one you're probably interested in is the speed constant Kv - how much faster does it spin for every additional volt applied. The theoretical max speed of the motor is simply V * Kv, but that doesn't leave any torque left. You'll want to pick a Kv fast enough that your theoretical max speed is higher than your target speed.The easiest way to calculate Kv is if you're re-winding an existing motor, or somehow already know the motor constant Km. Spin the motor at a known speed, measure the voltage, divide, and you have Kv. When you re-wind, increase or decrease the number of turns to proportionally change the new Kv. Twice the turns will halve the speed and double the torque.If you're starting from scratch, it is probably easier to calculate the torque constant Kt in a package like FEMM ( Finite Element Method Magnetics ). Then, use Kt = 1/Kv to find the speed constant.How do you wind a brushless motor for a specific voltage? Is there a formula? Could I get an example?5. i have a rc electric hammer and want to upgrade the battery and get a brushless motor?Not familiar with the hammer but I would call Hobby town usa, they will know, the only problem with this upgrade is the transmission, differentials, axles etc. wo not handle the power. You would be money ahead in the long run to get one that is already brushless. Traxxas has some good stuff at a good price. Check out the NEW e-maxx.6. Problem with ESC, brushless motor and Raspberry PiYou should not power the ESC through both battery and Pi's 5V pin 2, it may cause damage. Your BEC of the ESC may already be totally fried now. It happened to mine before.Your motor battery is already powering the ESC's BEC, so you should never connect the ESC's red wire to anything, because double-powering will cause voltage confusion (amper overload, I do not know what the right term for it). The white and ground cable are fine to be connected as per your diagram, but never connect the red one to any other power source7. Why people use Brushless motor?No brushes means: 1. You do not lose power because of friction with the brushes and 2. There are no brushes to wear out over time, so the motors can last almost forever :) This has several advantages: 1. You can either swap your brushed motor for a brushless one with the same *power output*, but since it's more efficient, it will make your car or plane run for longer on the same battery (because it gives you the same power output, but consumes less power from the battery), or 2. You can fit a motor which consumes the same amount of power from the battery - but since brushless is more efficient, this means more power, so your car or plane will drive for the same time on one battery pack, but can go faster Finally, you can get a lot more maximum performance out of the same sized brushless motor, because although for a brushed motor the brushes start to burn if you try to increase the power above the motor's limit, for a brushless there are no brushes to burn! So the only limit is that you have to keep the magnets below a certain temperature, because if they get too hot they lose their magnetism. The only disadvantage of a brushless motor is that you need a brushless speed controller to run it (it wo not run directly on the battery). And brushless ESCs are slightly more expensive than brushed ESCs for the same power, but they are still pretty cheap on ebay.
