Committed to the development and manufacturing of high-quality high-voltage brushless motors and controllers.

Brushless motor controller and a motor controller of the structure

by:Hoprio     2020-08-07
Brushless motor controller is a special kind of dc motor controller, it USES built-in sensors electronic commutation on the method of the electronic commutator, brushless motor controller is mainly in order to eliminate the wear and tear of the brush, and brush contact generated noise.

the stator winding of the motor to make more balanced three-phase y connection, and is similar to the three-phase asynchronous motor. On the rotor of the motor with the magnetization of the permanent magnet has, in order to detect the polarity of the motor rotor, inside the motor is equipped with position sensor. Drive by power electronic devices and integrated circuits, such as the position sensor signals and positive &negative, used to control the inverter bridge on and off of each power tube continuous torque is produced.

the structure, brushless motor controller and motor controller the similarities, there are the rotor and stator, and only has the structure of the motor controller instead; Have motor controller of the turn is winding, connected to a power output shaft, the stator is permanent magnet steel; Brushless motor controller of rotor is a permanent magnet steel, along with shell and output axis is linked together, the stator is winding coil, to remove a brush motor controller used for alternating electromagnetic field commutator brush, so called the brushless motor controller.
