Abstract

The invention relates to the field of motors, and discloses a motor stator and a motor, and the motor stator comprises a stator core which is provided with a plurality of grooves; a stator winding including a plurality of phase windings mounted on the stator core so as to be different from each other in electrical phase; wherein at least two branch windings in each phase winding are sequentially connected in series along the circumferential direction of the stator core; wherein each phase winding comprises a plurality of connecting parts located at the two axial ends outside a stator core groove, each connecting part comprises a groove outer end part of a first conductor section and a groove outer end part of a second conductor section, and each conductor section comprises a groove interior and two groove outer end parts located at the two axial ends outside the stator core groove and connected with the groove interior; by adopting the single conductor section, a small amount of intersection of the winding head is realized, the manufacturing process is simplified, 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] In the prior art, the stator winding includes various types of conductors, including U-shaped conductors and conductor segments. The coils of various types of conductors 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. The hairpin coils used in the prior art have many types, complex arrangement, complex manufacturing process, high production cost and low processing efficiency. Contents of the invention [0003] The invention provides a motor stator and a motor. By adopting a single conductor segment, a small amount of intersection of winding heads is realized, the manufacturing process is simplified, the production cost is reduced, and the processing efficiency is improved. [0004] For reaching this purpose, the present i...
