Abstract

Embodiments of the invention disclose a motor winding and a motor stator. The motor winding includes at least one first segmented coil assembly; Each of the first segmented coil assemblies includes Nfirst segmented coil units, and any of the first segmented coil units includes M first hairpin coils having different groove pitches; any of the first hairpin coils includes a first groove outer end portion, a first groove inner portion, a first groove outer turning portion, a second groove inner portion, and a second groove outer end portion which are sequentially connected, the first groove outer end portion and the second groove outer end portion oppositely extend in the circumferential direction, and the M first hairpin coils are arranged concentrically; and the N first segmented coil units of each of the first segmented coil assemblies are sequentially arranged in the circumferential direction, and portions in N*M grooves are distributed in two layers in the radial direction. According to the technical scheme of the embodiments of the invention, the complexity degree of a production process can be reduced, the production cost is reduced, and the processing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a motor winding and a motor stator. Background technique [0002] The stator winding of a hairpin motor is shaped like a hairpin. During the manufacturing process of the stator, the winding is first made into the shape of a hairpin, and then penetrated into the slot of the stator core, and then the end of the hairpin is welded according to the design in another section. [0003] The stator winding includes a plurality of hairpin coils, and the multiple hairpin coils are inserted into the slots of the stator core according to a certain arrangement to form the required windings of single-phase motors or multi-phase motors. There are many types of hairpin coils used in the prior art, and the arrangement is complicated. A large number of bus bars and bus bars are needed to connect the branches and neutral points of each phase winding. The manufacturing process is complicated, the pro...
