ABSTRACT:
An actuator driven by an electric motor of the polyphase or single phase induction type has a stator with power windings as well as a rotor. At least one fixed fluxed sensor independent of the power windings is provided. The at least one sensor is arranged in an air gap between the stator and the rotor of the induction type motor such that the voltages induced in the at least one sensor represent a measure of the magnetic flux existing in the air gap. The flux sensor which is a preferably sensing winding provides a flux signal. An output signal representing the instantaneous output torque of the motor is generated by multiplying the flux signal by the electric current flowing through one or more of the stator power windings.
