ABSTRACT:
A rotation phase control device which synchronizes the rotation phase of the rotor of a motor with a reference signal and which has a steady-state characteristic compensating circuit improves the starting characteristic of the motor by compensating characteristic control apparatus for varying the compensating characteristic of the compensating circuit based on whether or not the rotation phase of the rotor is within a predetermined synchronization range relative to the reference signal.
