Title:
MOTOR STATOR AND MOTOR APPLYING SAME
Document Type and Number:
WIPO Patent Application WO/2023/185367
Kind Code:
A1
Abstract:
The present invention sets forth a motor stator and a motor applying same. The motor stator comprises: a stator core having a stator slot, the stator slot comprising multiple slot layers, and the slot layers being arranged along a radial direction of the stator core; and a stator winding inserted into the stator slot, the stator winding comprising multiple first conductors and multiple second conductors, and the first conductors and the second conductors each comprising two straight line segment parts. The straight line segment parts of the multiple first conductors are located in two adjacent slot layers, respectively, the first conductors and the second conductors comprise two straight line segment parts, and one straight line segment part of a second conductor and one straight line segment part of a first conductor are located in the same stator slot. A polar distance of the stator winding is τ, the magnitude of the pitch of the second conductors is y2, the distance between straight line segment parts of two adjacent first conductors in the same slot layer is L1, and the distance between straight line segment parts of adjacent second conductors is L2. According to the present invention, it is possible to reduce the height of a bending part of a stator coil, improving motor efficiency.
