Abstract

The present invention discloses a motor stator and a motor. The motor stator comprises a stator iron core, wherein the stator iron core has a plurality of slots formed on a radial inner surface of thestator iron core and spaced apart by a predetermined slot pitch in a circumferential direction of the stator iron core; and stator windings, which are arranged on the stator iron core. The stator windings are three phases of stator windings, and the three phases of stator windings are sequentially connected in parallel in the circumferential direction of the stator iron core. Each phase of statorwinding comprises a first coil assembly, at least one second coil assembly and a third coil assembly which are sequentially arranged in a sleeving mode in the radial direction of the stator core. A completely-symmetrical structure is adopted on a magnetic circuit through a winding structure, so that the problem of circulating current generated by an asymmetric structure is eliminated; and each interphase busbar is canceled, so that direct connection in each phase is realized, branches and neutral points of each phase of winding are arranged on any layer of any groove, the complexity of a manufacturing process is reduced, the production cost is reduced, the material cost is reduced, and the processing efficiency is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of motors, and in particular to a motor stator and a motor. Background technique [0002] 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 production cost is high, and the processing efficiency is high. Low. Contents of the invention [0003] Through the winding structure, a completely symmetrical structure is adopted on the magnetic circuit, which eliminates the problem of circulating current caused by the asymmetric structure; c...
