Motor stator and motor

Abstract

The invention provides a motor stator and a motor, the motor stator comprises a stator winding, and the stator winding comprises a plurality of first conductor groups and a plurality of third conductor groups. The plurality of first conductor groups are sequentially arranged on the M-th layer in the radial direction of a stator core along the circumferential direction of the stator core, and the plurality of third conductor groups are sequentially arranged on the first layer in the radial direction of the stator core along the circumferential direction of the stator core. Each first conductor group comprises a first large conductor, a first conductor and a first small conductor, and each third conductor group comprises three identical third conductors, or each third conductor group comprises a third large conductor, a third conductor and a third small conductor. According to the technical scheme of the motor stator provided by the embodiment of the invention, bus bars and busbars connected in parallel among all phase windings in the related technology are canceled, heat dissipation is uniform, power and torque are improved, a wiring mode is simplified, the complexity of a 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, eliminate bus bars and bus bars, achieve uniform heat dissipation, increase power and torque, simplify wiring methods, further reduce the complexity of the manufacturing process, reduce production costs, and improve processing efficiency.
