Abstract

The invention provides a motor winding and a motor stator. According to the motor winding, N first sectional type coil units and M second sectional type coil units are sequentially arranged in the circumferential direction, the first in-groove part and the second in-groove part of each first sectional type coil unit are distributed in two layers in the radial direction, and the first sectional type coil units are arranged on any layer of the motor winding in the radial direction; the third in-groove part and the fourth in-groove part of each second sectional type coil unit are distributed on the same layer in the radial direction, and the second sectional type coil units are arranged on the outermost layer and the innermost layer of the motor winding in the radial direction. According to the winding structure, a completely symmetrical structure is adopted in a magnetic circuit; the problem of circulating current generated by an asymmetric structure is eliminated, busbars among phases are canceled, direct connection among the phases is realized, branches and neutral points of windings of each phase are arranged on any layer of any groove, the complexity of a manufacturing process isreduced, 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, in particular to a motor winding and a motor stator. 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] The invention provides a motor winding and a motor stator. The winding structure adopts a completely symmetrical structure on the magnetic circuit, which eliminates the problem of circula...
