Abstract
PURPOSE:To improve the safety of the motor under effective control by varying the operating state of the motor regardless of the length of the time of the stable point of the predetermined level at a detector having two stable points at constant level and pulse train and retaining the state. CONSTITUTION:Since a power switch 3 is closed to allow DC current to flow through a diode 7, resistors 8, 10 and 11 toward the light emitting side of a photocoupler 12 and Cds of light receiving side to become low resistance, a three-terminal bidirectional thyristor 4 turns on to permit the motor 2 to start no load operation. Thus, the detector 16 repetitively become on and off, but a voltage is applied to the detector 16 by delaying the time until load is applied to the motor 2 with the delay circuit having transistors 18, 20, resistors 19, 21, 23 and capacitor 22. When the load is applied then to the motor 2, since the detector 16 is in off state, the motor continues rotating, while when the motor become no load state, the detector 16 becomes repetitively on and off to allow the thyristor 4 to turn on to stop the motor 2 continuously until the switch 3 is opened. In this manner it can secure the safety.
