ABSTRACT:
An improved arrangement for regulating the speed of an asynchronous motor in which an real performance regulator is inserted between the speed regulator and the means controlling the input voltage and/or current to the motor. The subsidiary regulator inserted between the speed control and the motor control circuits receives as an input a value of the real power which is proportional to the torque or traction force thereby resulting in linear control of the motor based on its actual performance.
