Abstract
The present document relates to an electric drive unit, comprising: a stator configured to produce a stator magnetic field, at least a first rotor including first rotor windings, the first rotor windings for instance including multi-phase windings, and at least a first inverter electrically connected with the first rotor windings and configured to produce an electric current in the first rotor windings for producing a first rotor magnetic field. The stator magnetic field is configured to interact with the first rotor magnetic field to exert a torque on the first rotor. The present document further relates to a method of operating the electric drive unit.
