Abstract
PURPOSE:To avoid an idling rotation by a method wherein a load variation signal of a motor is applied on a base of a transistor, and a collector thereof is connected with a signal output circuit and a signal is generated when a load of the motor is lessened. CONSTITUTION:A voltage difference is applied between a collector and an emitter of a transistor 1 respectively through resistors r1, r2 with a regulated voltage supply 2. A load variation signal generated through a combined method A, etc. which consists of a current transformer and a converter is applied on a variable resistor 3 by means of varying voltage. By connecting an output terminal with a base terminal of the transistor 1 through a rsistor r3, the transistor 1 is rendered nonconductive when the motor is put into a idling status, and reaches a condition wherein its current is lower than a no load status. When the transistor becomes nonconductive, an output signal circuit B generates a signal to stop the motor.
