ABSTRACT:
The rotation speed of a brushless motor is detected to generate a signal synchronizing with the rotation of the motor, and, on the basis of the synchronizing signal, a plurality of duty signals representing respectively different duty factors are generated. One of the plural duty signals is selected according to the detected rotation speed of the motor, and, on the basis of the selected duty signal, a corresponding exciting signal is supplied to the motor. The higher the detected rotation speed of the motor, the selected duty signal represents a larger duty factor.
