ABSTRACT:
A motor drive apparatus which drives a motor by controlling conduction
on-conduction of a drive transistor for causing a current to flow through a drive coil of the motor based on a pulse signal indicating a relative position between the rotor and stator of the motor, generated by a position detector, and on a rotation speed setting voltage for setting the rotation speed of the motor. The apparatus comprises a control circuit that generates a pulse-delayed signal by delaying the pulse signal by delay time according to the voltage level of the rotation speed setting voltage.
