Abstract

The invention relates to the technical field of driving devices, and discloses a stator assembly and a motor, the stator assembly comprises an iron core and a stator winding, the iron core is provided with a through hole, the inner wall of the through hole is provided with an even number of N stator grooves, and the N stator grooves extend along the axial direction of the through hole; an odd number M layers of hierarchical spaces are sequentially arranged in each stator slot along the radial direction of the through hole, the Mth layer of hierarchical space is defined as the hierarchical space closest to or farthest from the bottom wall of the stator slot in the M layers of hierarchical spaces, and the Mth layer of hierarchical space in the N stator slots is defined to form an outer layer space; defining hierarchical spaces except for the Mth layer of hierarchical space in the N stator slots to form an inner layer space; the stator winding comprises a plurality of sub-windings which are connected in a star-shaped or angle-shaped manner, each sub-winding comprises a plurality of hairpin coils, only short-distance hairpin coils or long-distance hairpin coils are arranged in the outer-layer space, and only whole-distance hairpin coils are arranged in the inner-layer space. The stator assembly provided by the invention is higher in insulation reliability.

Description

technical field [0001] The invention relates to the technical field of driving devices, in particular to a stator assembly and a motor. Background technique [0002] With the improvement of space utilization requirements of new energy vehicles, there is a trend of three-in-one or even multi-in-one integration of motors, electronic controls, and reducers, which also puts higher requirements on the power density of motors. In order to meet the high power density requirements of motors, flat wire stator winding motors are the future development direction of vehicle drive motors. Compared with round wire stator winding motors, flat wire stator winding motors have a higher slot fill rate, and the winding end The part is shorter, the power density is higher, and the heat dissipation capacity is stronger, which is especially suitable for the application requirements of miniaturization and light weight of vehicle drive motors. The basic component of the flat wire stator winding mot...
