Summary:PURPOSE:To enable to control the speed of a motor of multistage without speed floating by turning ON and OFF a commercial power source for a motor synchronously with the commerical frequency for a period multiplied by integer magnification of one period of the commercial frequency. CONSTITUTION:A control microcomputer 2 turns ON a full-wave rectification type semiconductor switch 1 synchronously with a commercial power source 3 during a period multiplied by integer magnification of one period of the power source 3. In this manner, the speed of the motor can be directly controlled in multistage through a semiconductor switch by a sole port of a microcomputer.
