Today let's say the control of the brushless motor controller. Brushless motor controller controller is a kind of control device, according to the need to protect the motor controller to control the speed of the motor controller. It has a long service life, good overload ability, low cost, high efficiency, etc. Simple, can be set up by relatively simple to start and stop the motor controller, so as to realize independent control operation. And its peripheral circuit adopts the technology of the reverse voltage commutation, can prevent some noise. But on the structure, it is more complex than a brush motor controller. Just think you don't have the carbon brush, so there is no carbon brush wear problem, can avoid crushing system, etc. Above all, everyone to understand whether the controller of brushless motor controller.
