A lubricant supported electric motor assembly includes an electric motor module, a shifting and first stage module, and a final drive module sequentially operably interconnected with one another for producing drive torque that is ultimately conducted to a wheel of a vehicle. The electric motor module includes a stator and a rotor defining an internal rotor cavity. The shifting and first stage module is disposed within the internal rotor cavity and includes a first planetary gear reducer assembly and an output gear selectively coupleable to said first planetary gear reducer assembly. The final drive module is disposed adjacent the shifting and first stage module and includes a second planetary gear reducer assembly operably coupled with the output gear. A shifting mechanism establishes selective coupling between the first planetary gear assembly and the output gear to transfer adjustable torque from the shifting and first stage module to the final drive device.

A voltage balanced winding for a stator of an electric machine with a high number of pole pairs is distributed over several circumferential sections and several radial layers of the stator. The winding consists of at least two phases and each phase of the winding comprises a plurality of conductor segments, one conductor segment for each layer in each sector. Each of the conductor segments comprises a plurality of straight conductor portions arranged in an axial direction of the stator and a plurality of end-windings connecting the straight conductor portions to a wave pattern. The voltage balanced winding is characterized in that the plurality of conductor segments is divided into branches of series connected conductor segments, wherein each branch includes at least D conductor segments selected from D different sections d and D different layers j such that (j+d) mod D equals a predefined number, with D being the number of circumferential sections. At least a first conductor segment of layer j1 and sector d1 and a second conductor segment of layer j2 and sector d2 with j1+d1=j2+d2 are integrally formed as an uninterrupted conductor segment.
