Abstract:
A stator assembly includes a plurality of stator slots, including a first stator slot defining a slot axis. A plurality of conductors is at least partially positioned in the first stator slot and forms a winding set. The assembly is characterized by uneven conductor lengths and a combination of series and parallel connections in the coil sets of the winding set. The winding set includes at least one coil set with the conductors connected in series and at least one coil set with the conductors connected in parallel. At least one of the conductors extends a first conductor length along the slot axis and at least another of conductors extends a second conductor length along the slot axis. The first conductor length is different from the second conductor length. The assembly results in reduced winding alternating current losses, enhanced motor torque and additional turn count options.
