Motor stator and motor

Abstract

The invention provides a motor stator, a motor and a stator winding. Each phase winding forms X branch windings in parallel connection by a plurality of long-pitch conductors and a plurality of short-pitch conductors along the circumferential direction of a stator core, and the long-pitch conductors surround the short-pitch conductors; the long-pitch conductor comprises a first long-pitch conductor, the interiors of two grooves of the first long-pitch conductor are located on two adjacent layers in the radial direction of the stator core, and the interiors of two grooves of the short-pitch conductor are located on two adjacent layers in the radial direction of the stator core; the long-pitch conductor of at least one phase winding further comprises a second long-pitch conductor, and the interiors of two grooves of the second long-pitch conductor are located on the first layer and the Mth layer in the radial direction of the stator core. By the adoption of the technical scheme, a bridging line is omitted, heat dissipation is uniform, power and torque are improved, the wiring mode is simplified, then the process is simplified, and machining 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 hairpin coils, and the multiple hairpin coils are inserted into the slots of the stator core according to a certain arrangement to form the single-phase winding or multi-phase winding of the required motor. The hairpin coils used in the prior art There are many types, so the stator winding needs to use a large number of bridge wires to connect the branches of each phase winding, the arrangement of the stator winding is complicated, the forming is difficult, the production cost is high, and the processing efficiency is low. Contents of the invention [0003] The main purpose of the present invention is to provide a motor stator and motor, eliminating bridge wires, uniform heat dissipation, increased power and torque, simplified wiring methods, further simplified processes, and improved proc...
