Motor stator and motor

Abstract

The invention provides a motor stator and a motor. The motor stator comprises a stator winding, the stator winding comprises a plurality of first conductor groups and a plurality of second conductor groups, the plurality of first conductor groups are sequentially arranged on the Mth layer in the radial direction of a stator core along the circumferential direction of the stator core, and the plurality of first conductor groups are sequentially arranged on the first layer in the radial direction of the stator core along the circumferential direction of the stator core; the plurality of second conductor groups are sequentially arranged on the (N + 1) th layer and the (N + 2) th layer in the radial direction of the stator core along the circumferential direction of the stator core, and N is an odd number; and each first conductor group comprises at least one first large conductor and at least one first small conductor, and each second conductor group comprises a second large conductor, a second conductor and a second small conductor. According to the technical scheme of the motor stator provided by the embodiment of the invention, bus bars and bus bars connected in parallel among all phase windings in the related technology 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.
