Abstract

The invention discloses a stator assembly and a motor with the same, and a vehicle, wherein the stator assembly comprises a cylindrical stator iron core, a stator winding, a neutral wire and a plurality of connecting blocks, wherein the stator iron core is provided with a plurality of stator grooves which are arranged at intervals along the circumferential direction of the stator iron core; the stator winding comprises a plurality of conductor sections, wherein each conductor section comprises a groove inner part which is arranged in the corresponding stator groove of the stator iron core, anda first end and a second end, wherein the first end and the second end are arranged outside the stator iron core; the groove inner part is connected between the first end and the second end; the second ends of the plurality of conductor sections form a welding end; the star point outgoing lines of all phases of the stator winding are located on the welding end; the neutral wire surrounds the welding end of the stator winding in the circumferential direction; each connecting block has an accommodating space; and the neutral wire penetrates through and are welded in the accommodating spaces soas to be connected to the star point outgoing lines of each phase of the stator winding. According to the stator assembly provided by the invention, the occupied space is reduced, and the structure iscompact.

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...
