Document Type and Number:
Japanese Patent JPH06296
Kind Code:
A
Abstract:
PURPOSE: To prevent the occurrence of noises and radio wave interference and reduce the cost by controlling the revolving speed of a motor.
CONSTITUTION: The revolving speed of a motor 10 is detected by a revolving speed detecting means 33, and a control circuit 34 excites both the main coil and the auxiliary coil of the motor 10 or excites either one of them by selective control based on the revolving speed of the motor 10 to control it. Few noises are generated unlike the pulse extraction control of the AC wave-form, and little current distortion is generated unlike the phase control or chopper control.
