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 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 thestator winding is arranged on the welding end, the neutral line encircles the welding ends of the stator winding along a circumferential direction and is connected with the star-point leading-out line, and an avoidance space is limited between the neutral line and the welding end and is suitably used for accommodating a winding arranged between the star-point leading-out line of two adjacent phases. The stator modlue disclosed by the invention is low in occupancy space.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a stator assembly, a motor and a vehicle with the same. Background technique [0002] In the related art, the neutral line has a UV connecting line connecting the neutral point connecting portion of the U-phase winding to the neutral point connecting portion of the V-phase winding and a UV connecting line connecting the neutral point connecting portion of the V-phase winding to the neutral point connecting portion of the W-phase winding. The VW connection line connected to the neutral point connection part. The neutral wire in the above technology is connected by two U-shaped wires to connect the three connecting parts two by two, which will result in thicker welding parts in the middle, take up a large space, and the welding performance is difficult to guarantee. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems exist...
