TORQUE CONTROLLER FOR DIFFERENTIAL ACTUATOR

摘要

The rotation control apparatus includes two induction motors and a differential mechanism for producing a constant torque on its output shaft based on the differential speed of the induction motors. The apparatus includes two inverters each located between one of the induction motors and a common power source for the induction motors and having individual voltage/frequency output characteristics. The inverters set separately the voltage/ frequency output characteristics of power supplied to the induction motors so as to control the speed of the induction motors separately.
