Title:
STATOR AND MOTOR
Document Type and Number:
WIPO Patent Application WO/2021/065298
Kind Code:
A1
Abstract:
This stator comprises: a stator core having a plurality of teeth; a plurality of pins each having an acting part that extends in the axial direction within a slot between adjacent teeth; and a plurality of bus bars that are electrically connected to the respective pins. In each of the slots, the acting parts are radially arranged in multiple tiers. Each of the pins has: two acting parts that are arranged so as to straddle teeth; a first pin 51 and a second pin 52 that have a connection part that circumferentially connects the acting parts; and a third pin 53 that is connected to a corresponding one of the bus bars. The respective acting parts of the second pin 52 and the third pin 53 are arranged in either the outermost tier or the innermost tier of the slot. The number of teeth that the second pin straddles is less than the number of teeth that the first pin straddles. This pin arrangement enables facilitating ease of producing a motor that is equipped with a sheet coil.
