Document Type and Number:
WIPO Patent Application WO/2021/009792
Kind Code:
A1
Abstract:
This stator (3) has a stator core (31), three-phase coils (32) attached to the stator core (31) in a distributed winding manner, and a lacing material (34). A first phase coil is a coil through which the largest current flows among the three-phase coils (32) when current flows through the three-phase coils (32) from a power supply for magnetizing a magnetic body (22). The first phase coil has a first region 35a, a second region 35b, and a third region 35c. The lacing material (34) has more turns in the first region (35a) than in at least one of the second region (35b) and the third region (35c).
