Title: REDUNDANT ELECTRICAL MACHINE FOR DRIVING A MEANS OF PROPULSION
Abstract:
The invention relates to an in particular redundant electrical machine for driving a means of propulsion with increased reliability. The machine comprises, for example, two sub-machines, each consisting of a stator winding system and a rotor, wherein the two rotors are arranged in a rotatably fixed manner on a common shaft, by means of which the means of propulsion is ultimately set into motion. The invention further relates to a sliding device which, in case of a failure in one of the stator winding systems, has the effect that, for the corresponding faulty sub-machine, the air gap between the affected stator winding system and the associated rotor is enlarged such that the electromagnetic interaction between said components is inhibited.
