Abstract
PURPOSE: To make limmiter compact by making the control of torque electrically.
CONSTITUTION: The voltage limmiting circuit 10 to dispatch a voltage feedback signal when the primary voltage of motor exceeds a predetermined value is provided between the differential amplifier 7 for controlling speed and the induction motor 3. If, as an induction motor with such a circuit constitution, a high-resistance induction motor in which generation torque is affected by slip to a lesser extent is used, the generation torque can be controlled by limmiting the primary voltage and also the transmission of max. torque to load can be prevented. Thus, it is possible to make it more compact than the conventional type mechanical torque limmiter and also to set up limmited torque value simply.
