A switching arrangement for discharging an energy storage device of a motor vehicle including an energy storage device that stores electrical energy and supplies an electrical machine of a motor vehicle, a discharging circuit having a discharging resistor, a voltage comparison element and an activation switching device. The activation switching device starts discharging the energy storage device via the discharging resistor at the end of a delay period after the motor vehicle has been switched off. The voltage comparison element compares the prevailing voltage of an energy storage voltage and a voltage threshold value and terminates the procedure of discharging the energy storage device if the prevailing voltage of the energy storage device is less than or equal to the voltage threshold value.

An electric machine comprises a rotor () equipped with permanent magnets (), and a stator () equipped with electromagnetic poles. The electric machine is characterized in that several adjacent electromagnetic poles respectively constitute an electromagnetic pole group in which the adjacent electromagnetic poles are spaced apart at a first electromagnetic pole spacing, that adjacent electromagnetic poles belonging to different electromagnetic pole groups are spaced apart at an electromagnetic pole spacing greater than said first electromagnetic pole spacing, that each electromagnetic pole group has an even number of electromagnetic poles, and that adjacent electromagnetic poles of an electromagnetic pole group are linked to each other so as to generate magnetic fields of opposite direction in operation.

For obtaining a compact superconductive power switch for rapid switching speeds and with high dielectric strength, several winding layers ( ) with several windings each are lined up adjacent each other in axial direction. Between individual layers ( ), there are provided cooling/heating elements ( to ) in order to transfer the high-current switch unit ( ) to the superconducting state and the normally conducting state, respectively, by cooling/heating, i.e. for closing and opening said unit, respectively. Mutually adjacent current conductors have the switching current flowing therethrough in opposite directions, so that the high-current switch unit ( ) is of low induction, which permits fast switching times in particular when the switch is opened by an additional current pulse. Due to the numerous windings of the current conductor sections in each layer and the plurality of layers in axial directions, only a low voltage differential results between the adjacent current conductors, and an assembly with high dielectric strength is obtained in total.
