Motor stator and motor

Abstract

The present invention provides a motor stator and a motor, and the stator comprises a stator core having Y slots formed on a radially inner surface of the stator core and spaced apart by a predetermined slot pitch in a circumferential direction of the stator core; a stator winding which comprises a plurality of phase windings mounted on the stator core, wherein each groove is divided into M layersby the number of the phase windings in the grooves which can be accommodated in the radial direction of the stator core, and M is an even number greater than or equal to 4; the number K of grooves ofeach pole and each phase of the stator winding is greater than or equal to 2, and each phase winding is X * K parallel branch windings. According to the technical scheme of the motor stator in the embodiment of the invention, bus bars and bus bars which are 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 of a manufacturing process is further reduced, the production cost is reduced, and the processing efficiency is improved.

Description

technical field [0001] The present invention relates to the field of motors, and 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 slots of the stator core according to a certain arrangement to form the three-phase windings of the required motor. In the prior art, it is necessary to use between each phase winding A large number of bus bars and bus bars are connected to the phase windings, the arrangement of the stator windings is complex, the forming is difficult, the production cost is high, and the processing efficiency is low. SUMMARY OF THE INVENTION [0003] The main purpose of the present invention is to provide a motor stator and motor, which eliminates bus bars and bus bars, dissipates heat evenly, increases power and torque, and simplifies wiring methods, thereby reducing the complexity of the manufacturing proces...
