Title:
MOTOR STATOR AND MOTOR USING SAME
Document Type and Number:
WIPO Patent Application WO/2023/185368
Kind Code:
A1
Abstract:
The present invention provides a motor stator and a motor using same. The motor stator comprises a stator iron core provided with stator slots, the stator slots comprising a plurality of slot layers, and the slot layers being arranged in the radial direction of the stator iron core; and a stator winding inserted into the stator slots, the stator winding comprising a plurality of first conductors and a plurality of second conductors, and the first conductors and the second conductors each comprise two straight segment parts, wherein the straight segment parts of the plurality of first conductors are respectively located in two adjacent slot layers, the first conductors and the second conductors each comprise two straight segment parts, and one straight segment part of one second conductor and one straight segment part of one first conductor are located in a same stator slot; a pitch of the first conductors is y1, a pitch of the second conductors is y2, a polar distance of the stator winding isτ, a distance between the straight segment parts of two adjacent first conductors in a same slot layer is L1, and a distance between the straight segment parts of two adjacent second conductors is L2. The present invention can decrease the height of a bending part of a stator coil and improve the efficiency of a motor.
