The invention provides a stator punching sheet, and a motor, a compressor and a household electrical appliance comprising the stator punching sheet. The stator punching sheet is provided with a rotor hole, and also comprises a yoke part and a plurality of stator teeth, wherein the yoke part is formed at the periphery of the stator punching sheet, the stator teeth are arranged at intervals along the inner circumference of the yoke part, each stator tooth comprises a tooth body and a tooth boot, one end of each tooth body is connected with the yoke part, the other end of each tooth body is connected with the tooth boot, an adjusting groove is formed in the side, facing the rotor hole, of the tooth boot, the stator tooth is divided into a first area and a second area by the center line of the tooth body, the first area is located on the upstream of the rotor rotation direction, the second area is located on the downstream of the rotor rotation direction, the area, located in the first area, of the adjusting groove is S1, the area, located in the second area, of the adjusting groove is S2, and S1 is smaller than S2. According to the invention, the problem that the radial force density of a unidirectional rotating motor cannot be effectively weakened in the prior art is solved.
Description
technical field [0001] The invention relates to the technical field of motors, in particular to a stator punch, and a motor, a compressor and a household appliance using the stator punch. Background technique [0002] Based on the operation characteristics of the bidirectional rotation of the motor, the stator teeth of the existing motor are left-right symmetrical, and the length of the air gap between the stator tooth shoe and the rotor is also symmetrical. The purpose of adopting this symmetrical structure is two points, namely, to satisfy the bidirectional rotation of the motor; and to avoid introducing excessive magnetic field harmonics. However, for a unidirectional rotating motor, this symmetrical structure limits the structural design of the unidirectional rotating motor. Moreover, this symmetrical structure cannot greatly weaken the radial force density of the motor. Contents of the invention [0003] The present invention proposes a stator stamping and motors, c...
