ABSTRACT:
An eddy-current intermediate rotor (13) is fixed to the motor shaft (9) and is arranged to be rotatable between the stator-iron poles and the permanent-magnetic rotor (15) which is mounted for free rotation on the motor shaft (9). The rotor (15) and the eddy-current intermediate rotor (13) are disc-shaped and form a disc assembly (23) which can be axially magnetized via the stator-iron poles (3) on each side of the disc-assembly (23). A centrifugal coupling is provided, which acts to couple the rotor (15) to the eddy-current rotor when the disc assembly has come up to speed.
