WebJun 16, 2024 · If you apply power to the motor, the shaft turns. Conversely, if the motor shaft is turning, it will generate a voltage. When a BEMF decoder applies power to a motor as pulses (PWM), there is a time between pulses when no voltage is applied to the motor. During this time the decoder can “read or sense” the voltage produced by the motor.
