Document Type and Number:
Japanese Patent JPWO2021161403
Kind Code:
A1
Abstract:
A stator (3) has a stator core (31) and three-phase coils (32) attached to the stator core (31) in a distributed winding manner. The three-phase coils (32) have 6×n U-phase coils (32U), 6×n V-phase coils (32V), and 6×n W-phase coils (32W) at coil ends (32a). Each of the 6×n U-phase coils (32U), 6×n V-phase coils (32V), and 6×n W-phase coils (32W) includes 2×n sets of coil groups each including first to third coils. At the coil ends (32a), the 2×n sets of coil groups are arranged at equally-spaced intervals in the circumferential direction of the stator (3). At the coil ends (32a), the first to third coils are arranged at two slot pitches in that order in the circumferential direction. At the coil ends (32a), at least two of the first to third coils of at least one phase are adjacent to each other in the radial direction.
