Abstract:
Provided is a stator assembly, comprising: a stator core (1); a plurality of tooth parts (2) arranged on an inner side wall of the stator core (1), wherein the plurality of tooth parts (2) are distributed in a circumferential direction of the stator core (1), a groove part (20) is defined between adjacent tooth parts (2), and the tooth parts (2) comprise a first tooth; and a winding (3), wherein the winding (3) is arranged on the tooth parts (2) in a winding manner, the winding (3) is wound from the first tooth, and when wound on other tooth parts (2), the winding (3) passes through the groove parts (20) on two sides of the first tooth for wire spanning. The winding (3) starts to be wound from the first tooth, and after the winding of the first tooth is completed and when the winding of other tooth parts (2) starts, the winding needs to pass through the groove parts (20) on the two sides of the first tooth for wire spanning, such that a spanning wire of the same winding (3) is concentrated in one area, that is, collecting inside the groove parts (20) on the two sides of the first tooth, and taps may be led out from the groove parts (20) on the two sides of the first tooth, and the taps are concentrated in one area to make wiring easy.
