  • Electric machine and use thereof
    Patent number: 9787207
    Abstract: An electric machine is selectively operated as a transformer for AC voltage operation or as a throttle system for DC voltage operation. A transformer core has two limbs. An additional winding with a first additional partial winding is wound around a first limb and a second additional winding is wound around the second limb. A higher-voltage winding with a first higher-voltage partial winding is wound around the first additional partial winding and a second higher-voltage partial winding is wound around the second additional partial winding. A first traction winding is wound around the first higher-voltage partial winding and a second traction winding is wound around the second higher-voltage partial winding. A first DC voltage winding may be wound around the first traction winding and a second DC voltage winding may be wound around the second traction winding.
