ABSTRACT:
The coupling is constructed for synchronous as well as asynchronous operation. To this end, the driving rotor and driven rotor are each provided with tooth-like poles and the poles of one rotor are spaced apart to cover only a part of the rotational surface of the rotor. The remaining part of the rotational surface is covered by smooth electrically-conductive layers. A circumferential band may also be disposed about or within a rotor in facing relation to the poles of the other rotor while being of smaller width than the air gap between the two rotors. For increased asynchronous operation, conductor rods are disposed between the poles of the rotors.
