Abstract

The invention discloses a stator module and a motor and vehicle with the same. The stator module comprises a cylindrical stator core, a stator winding and a neutral line, wherein a plurality of statorgrooves are formed in the stator core and are arranged at intervals along a circumferential direction of the stator core, the stator winding comprises a plurality of conductor segments, each conductor segment is made of a flat wire, each conductor segment comprises a groove part, a first end and a second end, the groove part is arranged in the stator groove of the stator core, the first end and the second end are arranged outside the stator core, the groove part is connected between the first end and the second end, the second ends of the plurality of conductor segments form welding ends, a star-point leading-out line of each phase of the stator winding is arranged on the welding end, the neutral line encircles the welding ends of the stator winding along a circumferential direction and comprises an arc connection piece and a plurality of touch angles, and the plurality of touch angles are connected with a star-point leading-out line of each phase of the stator winding. The stator module disclosed by the invention is simple in structure, and the occupancy space is reduced.

Description

Technical field [0001] The present invention relates to the technical field of electric motors, in particular to a stator assembly, an electric motor and a vehicle having the same. Background technique [0002] In the related art, the neutral wire has a UV connection wire connecting the neutral point connection part of the U-phase winding and the neutral point connection part of the V-phase winding, and the neutral point connection part of the V-phase winding and the middle point of the W-phase winding. VW connection line connected to the sex point connection part. In the above-mentioned technology, the neutral wire is connected by two U-shaped wires to connect the three connection parts two by two, which will cause the middle welding part to be thicker, occupy a large space, and the welding performance is difficult to guarantee. Summary of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason...
