Embodiment Construction
[0015] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.
[0016] see figure 1 As shown, the above-mentioned stator includes a stator core, and the stator core is provided with at least one set of A phase, b phase, C phase, a phase, B phase, and c phase arranged in sequence, and each phase includes at least two sets of pitch. In this embodiment, each phase includes two sets of pitches.
[0017] The above-mentioned stator also includes a one-to-one corresponding element winding 1 arranged in the pitch, a B-phase auxiliary winding 2 wound on the A phase, an A-phase auxiliary winding 3 wound on the C phase, and a B-phase auxiliary winding wound on the B phase. Phase C auxiliary winding on phase 4. From figure 1 It can be seen that the B-phase auxiliary winding 2 is adjacent to the b-phase, the A-phase auxiliary winding 3 is adjacent to the a-phase, and the C-phase auxiliary winding 4 is adjacent to t...
