ABSTRACT:
A digital motor drive control system comprises drive means for performing phase switching by use of the phase timing signal from phase switching timing generating means and driving of the motor in response to a PWM clock signal generated by PWM signal generating means where means is provided for synchronizing the PWM clock signal of the PWM signal generating means with a phase switching timing. The number of PWM clock pulses of each phase of the motor is made equal to each other, so that rotational irregularities of the motor are decreased.
