Abstract

The present invention discloses a motor stator and a motor. The motor stator comprises: a stator core having a plurality of slots formed on a radial 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 which is installed on the stator iron core. The stator winding is provided with Q pole pair numbercoils, and Q / the number of slots per pole per phase is equal to P, P being an integer; the stator winding has three phases, and the number of slots per pole per phase is 3; and the stator winding comprises a first coil assembly and a third coil assembly which are sequentially arranged in a sleeving mode from outside to inside. The adopted coil units are few in type and simple in arrangement mode,use of bus bars and busbars can be reduced, branches and neutral points of all phases of windings can be arranged on any layer of any groove, then the complexity degree of the manufacturing process isreduced, the production cost is reduced, and the machining efficiency is improved.

Description

technical field [0001] The invention relates to the technical 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 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 embodiment of the present invention provides a motor stator and a motor, the types of coil units used are few, the arrangement method is simple, the use of bus bars and bus bars can be reduced, and the branches and ne...
