The invention discloses a stator assembly and a motor and a vehicle thereof. The stator assembly includes: a cylindrical stator core with a plurality of stator slots; a stator winding with a plurality of conductor segments; Each of the conductor segments 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, and the in-slot portion is connected to the first end and the second end In between, the second ends of the plurality of conductor segments form welding ends, and the star-point lead-out lines of each phase of the stator winding are located on the welding ends, and the wire ends of the star-point lead-out lines of each phase of the stator winding are along the radial direction of the stator core extending outward and bending at a preset angle to form a radial protrusion; a neutral line, the neutral line surrounds the welding end of the stator winding in the circumferential direction, and the neutral line is directly connected to the radial protrusion respectively. 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, the occupied space thereof can be reduced, and the structure is compact.
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...
