Abstract
A stator for an electric machine includes a stator core with a multi-phase winding arranged on the stator core. The stator core has a plurality of slots formed therein and defines a first axial end and a second axial end. The multi-phase winding includes multiple parallel paths for each winding phase, each parallel path completing multiple revolutions around the stator core, and each parallel path comprising a series of slot segments arranged in layers of the plurality of slots and end turns alternately connecting consecutive slot segments on the first axial end and the second axial end. A pitch of the end turns connecting the slot segments for at least one parallel path alternates between a first pitch on the first axial end and a second pitch on the second axial end, the second pitch being different from the first pitch.
