Abstract

The invention provides a motor stator and a motor. The motor stator comprises a plurality of stator modules arranged along the circumferential direction, multiple stator teeth and a stator winding, wherein each stator module comprises an arc-shaped stator yoke part, the stator teeth can be arranged on the arc-shaped stator yoke parts in the circumferential direction, the stator teeth sequentiallycomprise teeth root parts, teeth waist parts and pole shoe parts which are connected with one another from inside to outside in the radial direction of the arc-shaped stator yoke parts, the stator winding is wound on the arc-shaped stator yoke parts along the circumferential direction and can penetrate through a plurality of stator teeth, and a plurality of stator modules are arranged along the circumferential direction, so the pole shoe parts on the stator modules are encircled along the circumferential direction to form an outer ring matching surface matched with the motor rotor. The motor stator is advantaged in that the axial size of the motor can be reduced, so the motor is thinned, and the internal capacity of electrical equipment such as a washing machine can be improved by saving the 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...
