Abstract
The disclosure relates to an electrical drive device having: an inverter including an inverter unit for each phase; a control unit configured to control the inverter units by application of vector control; and a rotating electrical machine having a stator that includes a plurality of phase windings connected to the inverter units. Each of the phase windings includes a first part-winding and an electrically isolated second part-winding. The inverter units include a first phase module and a second phase module. The phase modules deliver the electrical phase assigned to the respective inverter unit in a separate and a mutually electrically isolated manner. The first part-winding is electrically connected to the first phase module and the second part-winding is electrically connected to the second phase module.
