Method for measuring the output torque of an asynchronous motor having a stator and a rotor comprising the steps of measuring the rotational frequency of the stator field of the motor, the rotational speed of the rotor, calculating a measurement value for the slip speed from the difference between the rotational speed of the rotor and rotational frequency of the stator field, and calculating a measurement value for the output torque form the slip speed and statistical performance characteristic values for the output torque intrinsic to the motor.
