Claims

[Scope of utility model registration request]

In a stationary Servius control device in which the secondary voltage of a wound induction motor is rectified by a rectifier and then recirculated to an alternating current power source via an inverter, thereby driving the induction motor at variable speed, there is a A chopper circuit is inserted into the stationary motor, and the inverter is energized at a constant side angle that minimizes the power factor angle, and the energization time ratio of the chopper is controlled via a speed control circuit. Servius control device.
