ELECTRICAL APPARATUS COMPRISING DRIVE SYSTEM AND ELECTRICAL MACHINE WITH RECONNECTABLE STATOR WINDING

• Electrical apparatus, comprising a drive system and an electrical machine for propulsion of a vehicle, wherein the electrical machine comprises at least one rotor and at least one stator winding and can be connected via a connection point to a three-phase network. The stator winding can be switched between at least a first position in which it is electrically controlled by the drive system during propulsion of the vehicle, and a second position in which it is divided into at least two separate and magnetically coupled three-phase windings for converting of a voltage level that is available in the three-phase network. One divided first three-phase winding, consisting of a first set of windings, at a rotor speed corresponding to the frequency of the three-phase network has a voltage corresponding to the voltage level at the connection point. One divided second three-phase winding, consisting of a second set of windings, is electrically matched to the drive system and the windings in the first set and the windings in the second set are each connected to each other via a switching layout.
