Abstract

PURPOSE: To ensure rotation control by feeding electric power to the motor through an AND action to be performed when the output of a timer circuit and the voltage developed across a thristor are zero, it is suspended simultaneously with the stoppage of the timer circuit.
CONSTITUTION: A motor 5, a rectifier circuit 3 and a thyristor 4 are connected in series to a power source. A switching transistor 8 is provided to detect a voltage between the anode and the cathode of the thyristor 4 and turn thereof on and off, while an output terminal 9a of a timer circuit 9 composed of a switching circuit 13 and a charge/discharge circuit 14 is connected to the collector thereof. In operation, the power is fed to a motor 5 when a thyristor conducts by initial zero output in the actuation of the timer circuit while the transistor 8 is off, and suspended simultaneously with the stoppage of the timer circuit 9. In this manner, rush of current into the thyreistor can be prevented, while ensuring accurate energization and stoppage of the motor.
