Abstract

The method involves effecting two detections of torque values delivered by an AC motor (1) at an actuator (3) of the motor. One value is delivered by the motor via processing unit using voltage signals of phase and current signals of two phases as input signals. The torque value is compared with preset torque thresholds. Interruption of electric power to the motor is commanded when the torque value exceed the threshold limits. An independent claim is also included for a torque detection device for a three-phase motor using a control device comprising an incremental bi-directional encoder.
