Actually, brushless motor controller belongs to a kind of ac motor controller, is a kind of three-phase ac permanent magnet motor controller, input model of brushless motor controller 3 wire current is the alternating current (ac), the alternating current (ac) is not only the general mains of 50 hz sine wave, but through the controller (brushless motor controllerCommonly known as brushless electric adjustable)Modulation of a three-phase alternating rectangular wave, the frequency is higher than 50 hz a lot, and as the rotational speed of brushless motor controller. Myth of brushless motor controller are all have? 1, motor controller is not a bad mistake, brushless motor controller will be bad. Coil short circuit, for example, foreign body into the motor controller, controller and motor overload, overheating, cause magnet demagnetization. Don't use when installing motor controller long screw, screw into the cover of a motor controller length 2 - againBest 3 mm. Automotive brushless motor controller is generally fully enclosed, such as hacker c40 series. Gear motor controller than to the right, this motor controller does not overheat. My personal experience, automotive brushless motor controller of the tooth than in 1:5 -12 basic will not overheat between motor controller. 2, torque and the rotational speed and the motor controller is the same as the wrong, you have to take a in the torque and rotational speed. An indicator is high, then another must discount. This is why more than to prepare a brushless motor controller. Conclusion is correct. No matter what don't expect unlimited high speed, torque motor controller is infinite. Both will only take one. For electric room, should be under guarantee enough torque to get the highest speed. But there are equivalent and brushless motor controller, under the same speed, brushless torque is somewhat higher; Under the same torque, rotating speed is somewhat higher. In all speed by torsion, the product of the brushless is higher than a brush. This is because its efficiency is higher than a brush. 3, do not need to maintain, need to clean up the motor controller, replacement of bearings, magnet magnetization, to keep the best performance. Any damage to the motor controller can make the motor controller can't work daily maintenance mainly dust on the surface of the motor controller, and near the bearing and spilled oil mixed sludge, for bearing oiling. As long as pay attention to not let the motor controller overheating (magnetsDon't too small teeth than, smooth to keep the car drive system)Generally does not require any maintenance. Anyway, I could not open it! My request is not high, but I believe that the performance of the motor controller as long as reasonable use, basic won't fall! A lot of people have seen the model with brushless motor controller, batteries, they use so a lot of people there has been such a misunderstanding in the knowledge, thought the brushless motor controller is a dc motor controller, actually otherwise, brushless motor controller belongs to ac motor controller, is a kind of three-phase ac permanent magnet motor controller, the input model brushless motor controller 3 wire current is the alternating current (ac), it's just, it is not a 50 hz ac mains sine wave, but from the brushless motor controller (controllerCommonly known as brushless electric adjustable)Three-phase alternating square wave modulation, frequency is higher than 50 hz, and the changes over the motor controller speed.
