Abstract

The present invention relates to the field of motors, and discloses a motor stator and a motor. The motor stator comprises: a stator core having a plurality of slots, wherein the slots are formed on aradially inner surface of the stator core and spaced apart by a predetermined slot pitch in a circumferential direction of the stator core; and a stator winding including a plurality of phase windings mounted on the stator core so as to be different from each other in electrical phase, wherein at least two branch windings in each phase winding are sequentially connected in parallel along the circumferential direction of the stator core, and the stator winding comprises an inner side coil assembly, a middle coil assembly and an outer side coil assembly which are sequentially sleeved along theradial direction of the stator core. According to the invention, a winding structure is adopted, and a completely symmetrical structure is adopted on a magnetic circuit, so that the problem of circulating current generated by an asymmetric structure is eliminated; and the busbars among the phases are cancelled, so that direct connection among the phases is realized, 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 invention relates to the field of motors, 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 or 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; cancels the busbar between each phase, rea...
