Abstract

PURPOSE: To vary the motor speed with a variable period of feeding AC power to the motor by means of a timer circuit which allows alternate repetition production and stoppage of the output and has a variable device for varying the duty cycle for the period of the production of the output so arranged in the controller as to vary the period for supplying AC power for the motor.
CONSTITUTION: In this controller, incorporated is a timer circuit 9 which allows alternate repetition of the production and stoppage of the output and has a variable device for varying the period of the production of the output and a switching transistor 8 which is adapted to detect the voltage across a thyristor 5 to repeat On and OFF alternately are incorporated in the controller. In addition, the collector of the transistor 8 is connected to the gate of the thyristor 5 and the collector of the transistor 8. In operation, the thyristor 8 is triggered only when the transistor 8 is OFF, that is, when the voltage across the thyristor 5 is almost zero while an output is produced from the circuit 9 to provide AC power for the motor.
