  • Square wave control principle of brushless motor

    Square wave control principle of brushless motor

    1.Theoretical basis of square wave control Square wave control is also called six-step control. In an electrical cycle, the motor has only six states, or the stator current has six states (three-phase bridge arm has six switching states). Each current state can be regarded as a vector torque in ...
