Abstract

The present invention relates to the field of motors, and discloses a motor stator and a motor, the motor stator comprising: a stator core having a plurality of slots formed on a radially inner surface of the stator core and spaced apart by a predetermined slot pitch in the circumferential direction of the stator core; and 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 the stator winding has three phases, the slot number of each pole and each phase is Q, the phase winding has P poles, and the two branch windings in each phase winding are sequentially connected in parallel along the circumferential direction of the stator core. 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, fewer U-shaped conductors are adopted, the manufacturing process is simplified, the height of a welding end is reduced, the production cost is reduced, and the machining efficiency is improved.
