Stator assembly and motor with same, and vehicle

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 and a neutral wire, 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 pluralityof conductor sections, wherein each conductor section comprises a groove inner part which is arranged in the corresponding stator groove of the stator iron core, and a first end and a second end, wherein the first end and the second end are arranged outside the stator iron core and are connected with the groove inner part; 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; and the neutral wire is an integrally formed part, and is connected with the star point outgoing lines of each phase. According to the stator assembly provided by the invention, the connection structure of the star point outgoing lines and the neutral wire can be simplified, the occupied space is reduced, the structure is compact, the occupied space of the machine shell and the end cover of the motor can be reduced as far as possible, and the requirement of miniaturization of the motor can be met.

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] Disclosed in the related art is a star-point neutral line connection method, which has a complex structure, takes up a large space, and needs to increase insulating materials to ensure electrical safety. [0003] Another neutral line connection method is disclosed in the related art. The neutral line has a UV connection line connecting the neutral point connection part of the U-phase winding to the neutral point connection part of the V-phase winding and connecting the V-phase winding The VW connection line that connects the neutral point connection part to the neutral point connection part of the W-phase winding. The neutral line in the above-mentioned technology is to connect three connecting parts two by two respectively by two U-shaped wires, which will cause the middle welding part to be th...

AI Technical Summary

Problems solved by technology

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 lead to thicker welding parts in the middle, take up a lot of space, and the welding performance is difficult to guarantee
