ABSTRACT:
A magnetic clutch has a rotatable input part with first magnets and a rotatable output part with second magnets, the output part being magnetically coupled to the input part. At least one sensor measures a magnetic field or its temporal differentiation and is positioned to measure the magnetic field or its temporal differentiation resulting from the interference of the magnetic field of the first magnets of the input part with the magnetic field of the second magnets of the output part. The output of the sensor is processed by an evaluation unit operative to determine at least one working parameter.
