  • Is a Permanent Magnet Motor Feasible? | Power

    2021-3-17 · Commutation—varying the polarity of the charge—starts the brushless motor and keeps it turning. Next, you need to control both speed and torque. Varying the voltage to the stator of a BLDC motor controls the speed. Modulating the voltage at higher frequencies lets you control the motor speed to an even greater degree.
