Motor stator and motor

Abstract

The invention provides a motor stator and a motor, the motor stator comprises a stator winding, the number of slots per pole and per phase of the stator winding is 3, each phase winding is K parallelbranch windings, the K parallel branch windings comprise a plurality of first conductor groups, a plurality of second conductor groups, a plurality of third conductor groups and a plurality of fourthconductor groups, and K is an integer greater than or equal to 2; and the first conductor groups are located on the Mth radial layer of the stator core, the fourth conductor groups are located on thefirst radial layer of the stator core, and the first conductor groups located on the Mth radial layer of the stator core and the fourth conductor groups located on the first radial layer of the statorcore are adjacently arranged in the circumferential direction of the stator core. According to the technical scheme of the motor stator in the embodiment of the invention, bus bars and bus bars whichare connected in parallel among windings of each phase in related technologies are canceled, heat dissipation is uniform, power and torque are improved, a wiring mode is simplified, the complexity ofa manufacturing process is further reduced, the production 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 U-shaped conductors, and the plurality of U-shaped conductors are inserted into the slot of the stator core according to a certain arrangement to form the three-phase winding of the required motor. In the prior art, it is necessary to use A large number of bus bars and bus bars connect the phase windings, and the arrangement of the stator windings is complex, difficult to form, high in production cost, and low in processing efficiency. Contents of the invention [0003] The main purpose of the present invention is to provide a motor stator and motor, eliminating bus bars and bus bars, uniform heat dissipation, increased power and torque, simplified wiring methods, further reducing the complexity of the manufacturing process, reducing production costs, and improving processing efficiency. ...
