Abstract

PURPOSE: To increase torsional torque in a vibration speed section where increase in the torsional torque of motor shaft has so far raised a problem by eliminating harmonic torque through speed control with the secondary current of the motor flowing only to the resistor.
CONSTITUTION: Upon end of on-action of a switch S1, an off-command is fed to a switch S2. Then, with the switch turned off, a controllable electric valve of an inverter IV is controlled in shift to such a control angle β that the output voltage reaches its highest level. Therefore, the current Id flowing through a converter turns to zero immediately and all the secondary current of the motor flows to a resistor LRH. This is confined to such a period that a detection circuit RSD sends output "1", namely a section where resonance increases the torsional torque of the motor. However, the section contains no harmonic component because the motor current flows only through the resistor.
