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 parallel along the circumferential direction of the stator core; each branch winding comprises a plurality of connecting parts which are positioned at two axial ends outside the stator core slot; the connecting part comprises a groove outer end part of the first conductor section and a groove outer end part of the second conductor section; each branch winding is provided with a specialconnecting part; the pitch of the special connecting part is different from the pitches of other connecting parts of the branch winding; a completely symmetrical structure is adopted on a magnetic circuit through a winding structure, the problem of circulating current generated by an asymmetric structure is solved, a single conductor section is adopted, little intersection of winding heads is achieved, the manufacturing process is simplified, the production cost is reduced, and the 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] 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. The winding structure adopts a completely symmetrical structure on the magnetic circuit, which eliminates the problem of circulating current caused by the asymmetric structure. A single conductor segment is used to realize a small amount of crossing at the winding he...
