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.
