Abstract
A method and arrangement is disclosed herein for making a stator winding arrangement with multiple phase shift end turns. The winding arrangement is configured for use with conductors provided in multiple parallel paths and in 2-6-6-2 slot sets in each phase.
Claims20
A stator for an electric machine, the stator comprising:
- a stator core with slots formed in the stator core;
- and
- a multi-phase winding arrangement positioned on the stator core, each phase of the winding arrangement including a plurality of conductors defining in-slot portions and end-turns connecting the in-slot portions, the in-slot portions arranged in layers in each of the slots, the plurality of conductors further defining a plurality of paths winding through the layers of the slots, each path of the plurality of paths making multiple wraps around the stator core, wherein the end-turns for each path include mostly standard end turns and at least two non-standard end turns, wherein the standard end turns are defined by a standard pitch and the non-standard end turns are defined by non-standard pitches different than the standard pitch.
A stator for an electric machine, the stator comprising:
- a stator core with slots formed in the stator core;
- and
- a multi-phase winding arrangement positioned on the stator core, each phase of the winding arrangement including a plurality of conductors defining in-slot portions and end-turns connecting the in-slot portions, the in-slot portions arranged in layers in each of the slots, the plurality of conductors further defining a phase belt comprising a plurality of paths winding through the layers of the slots, wherein the winding arrangement is further defined by four slots-per-pole-per-phase such that each pole of each phase of the winding arrangement is defined by a slot set having four slots with conductors arranged in the four slots in a 2-6-6-2 layer configuration.
