Abstract

The invention discloses a stator assembly and a motor and a vehicle with the same. The stator assembly includes: a cylindrical stator core with a plurality of stator slots arranged at intervals along the circumferential direction of the stator core; winding, the stator winding includes a plurality of conductor segments, each of which includes an in-slot portion disposed in the stator slot of the stator core, a first end and a second end disposed outside the stator core, the in-slot portion is connected Between the first end and the second end, the second ends of the plurality of conductor segments form a welded end, and the star point leads of each phase of the stator winding are located on the welded end, and the number of winding parallel branches of the stator winding is as many as The neutral line, the neutral line surrounds the welding end of the stator winding, and the multi-way star-point lead-out lines in each phase are combined and connected to the neutral line. According to the stator assembly of the present invention, the connection structure between the star-point lead wire and the neutral wire can be simplified, and the occupied space can be reduced.

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] A star-point neutral line connection method is disclosed in the related art. The star-point neutral line connection method has a complex structure, takes up a large space, and requires additional 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 wire in the above technology is connected by two U-shaped wires to connect the three connecting parts two by two, which will resul...
