Title:
STATOR AND MOTOR
Document Type and Number:
WIPO Patent Application WO/2021/065297
Kind Code:
A1
Abstract:
This stator includes: a stator core having a plurality of teeth; a plurality of pins each having an acting part axially extending in a slot between the teeth; and a plurality of bus bars electrically connected to the plurality of pins. In each slot, the acting part is arranged in multiple stages in a radial direction. The plurality of pins have: two acting parts disposed across the teeth; a first pin 51 and a second pin 52 having connection parts connecting the acting parts in the circumferential direction; and a third pin 53 connected to the bus bar. The acting part of the second pin 52 is disposed on one side among the outermost and innermost ends of the slot, and the acting part of the third pin is disposed on the one side or the other side among the outermost and innermost ends of the slot. The number of the teeth, across which the second pin is arranged, is two more than that of the teeth across which the first pin is arranged. By arranging the pins in this way, it is possible to improve the ease of production of a motor having a plate coil while achieving short-pitch winding.
