Abstract
An electric machine having a stator and a rotor is divided into sub-machine systems by winding sections of the stator or rotor that can be switched separately for each phase. A winding section of each phase is assigned to each sub-machine system. Each sub-machine system acts as an electric machine. The sub-machine systems can be operated individually or in combination, depending on the requirements placed on the electric machine; the winding sections are correspondingly switched for this purpose. The switching between the winding sections is advantageously carried out mechanically with a contact disc.
Claims16
An electric machine, comprising:
- a stator;
- a rotor;
- a plurality of sub-machine systems formed by dividing windings for each phase on the stator or on the rotor into separately switchable winding sections, each said winding section being assigned to each said respective sub-machine system for each said phase and each said sub-machine system being configured to act as an electric machine.
An electric machine, comprising:
- a stator;
- a rotor;
- one of the stator or the rotor including a plurality of sub-machine systems comprising separately switchable winding sections for each phase, and each said sub-machine system being configured to act as an electric machine.
