Abstract

The present invention proposes a motor stator and a motor, wherein the motor stator includes: a plurality of stator modules arranged in the circumferential direction, and the stator module includes: an arc-shaped stator yoke; a plurality of stator teeth, which can be arranged in the circumferential direction On the arc-shaped stator yoke, the stator teeth sequentially include tooth roots, tooth waists, and pole shoes that are connected to each other along the radial direction of the arc-shaped stator yoke; Wound on the arc-shaped stator yoke, and can pass through the plurality of stator teeth, wherein, a plurality of the stator modules are arranged along the circumferential direction, so that the pole shoes on the stator modules are along the An outer ring mating surface mated with the motor rotor is formed around the periphery. Through the technical solution of the invention, the axial dimension of the motor can be reduced to realize thinning of the motor, and for electrical equipment such as washing machines, the internal capacity can be increased by saving space.

Description

technical field [0001] The invention relates to the field of motors, in particular to a motor stator and a motor. Background technique [0002] For the motor used in the washing machine with direct drive technology, the axial size of the motor is required to be as small as possible, so as to increase the laundry capacity without increasing the size of the washing machine too much. [0003] In the related art, when a transverse flux motor is used in a washing machine, although the transverse flux motor has a high torque density, it still has the following defects: [0004] (1) The process is relatively complicated and the manufacturing cost is high. [0005] (2) Each phase of the transverse flux motor is a module, and multiple modules are arranged axially to achieve a modular configuration. Since the winding of each phase is ring-shaped, the total axial length of the motor is equal to the axial length of all modules In sum, when the motor is a multi-phase motor, the axial s...
