ABSTRACT:
A speed control apparatus for a motor has a driver for the motor. The motor's rotational speed is detected, and a signal from the detector is counted. Signals from the counter received as the input by another circuit, which outputs data representing irregularities in the detection signal once the motor has reached its constant speed. Correction information is supplied to the motor driver on the basis of the irregularity data.
