Abstract

PURPOSE: To provide an operation of gradually rising up a torque of the induction motor to a desired amount of the torque at the time of starting, by providing a self oscillation circuit, increasing a slip frequency when its equivalent speed frequency is below a certain value, in the loop for a feed-back of the equivalent speed frequency.
