Abstract

The invention provides a stator assembly, a motor and electrical equipment, the stator assembly comprises a stator iron core, the stator iron core comprises a yoke part and a stator main tooth, the stator main tooth comprises a tooth body, and the tooth root of the tooth body is connected with the yoke part; the tooth boot is arranged on the tooth top of the tooth body, a first auxiliary tooth and a second auxiliary tooth are arranged on the tooth boot, and a groove is formed between the first auxiliary tooth and the second auxiliary tooth; the winding is arranged on the stator main teeth; wherein the tooth boot is asymmetrically arranged relative to the tooth body bisector of the tooth body. The first auxiliary teeth and the second auxiliary teeth serve as modulation parts, and the effect of magnetic field modulation is achieved; besides, the tooth boots are asymmetrically arranged relative to the tooth body bisectors of the tooth bodies, air gap magnetic conductance distribution is changed, and part of harmonic waves are weakened, so that torque pulsation is reduced, and the vibration noise performance of the motor applying the stator assembly is improved.

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...
