Abstract

The invention provides a stator assembly, a motor and electrical equipment. The stator assembly comprises a stator iron core which comprises a yoke part, a first main tooth and a second main tooth, wherein the first main tooth and the second main tooth are arranged on the yoke part; the first main tooth comprises a first tooth boot and at least two first auxiliary teeth arranged on the first tooth boot, and a first groove is formed between every two adjacent first auxiliary teeth; the second main tooth comprises a second tooth boot and at least two second auxiliary teeth arranged on the second tooth boot, and a second groove is formed between every two adjacent second auxiliary teeth; wherein the angular bisector of the included angle formed between the first main tooth and the second main tooth is a reference line, and the first tooth boot and the second tooth boot are asymmetrically arranged relative to the datum line. According to the invention, the first tooth boot and the second tooth boot are asymmetrically arranged relative to the reference line, so that non-uniform distribution of air gap magnetic conductance is realized, and the number of air gap magnetic conductance cycles is reduced, thereby obtaining more working harmonics to improve the output torque of the motor.

Description

technical field [0001] The invention relates to the field of motor technology and electric appliances, in particular to a stator assembly, a motor and electric equipment. Background technique [0002] In related technologies, the motor adopts a built-in rotor structure to increase the strength of the fundamental air-gap magnetic field, so as to improve the efficiency of the motor. However, to further increase the fundamental magnetic field strength in this structure will often increase the cost of the motor or deteriorate the vibration and noise performance of the motor, thereby affecting the reliability of the motor; moreover, the degree of improvement of the fundamental magnetic field strength is limited, and the room for motor performance improvement is also small. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. [0004] To this end, the first aspect of the present invention provid...
