Novel winding washing machine motor stator iron core

Abstract

The invention discloses a novel winding washing machine motor stator iron core, which comprises an iron core body. The iron core body is arranged in an annular shape. The iron core body comprises a plurality of silicon steel strips; each silicon steel strip comprises a tooth part and a yoke part, a whisker part is integrally arranged at the outer end of the tooth part, a yoke part crease-resistantgroove and an injection molding positioning groove are formed in the inner end of the yoke part, the injection molding positioning groove is aligned to the tooth root of the tooth part, and the yokepart crease-resistant groove is aligned in the middle position of two adjacent tooth parts; a plurality of buckling points are integrally arranged on the tooth part; and a plurality of buckling grooves matched with the buckling points are formed in the end face of the other end, opposite to the buckling points, of the tooth part. According to the technical scheme, the structural design is reasonable, the structure is simple, the inner end of the yoke part is not prone to wrinkling, the outer end of the yoke part is not prone to tearing, the tooth part is not prone to buckling deformation, lamination gaps are small, and practicability is good.

Description

technical field [0001] The invention relates to the technical field of motor stator cores, in particular to a novel wound stator core for washing machine motors. Background technique [0002] The biggest advantage of the roll-up process is the saving of raw materials, easy realization of automated production and improvement of production capacity and production efficiency. With the continuous improvement of my country's manufacturing industry level, the development of processing technology in various industries, especially the leap-forward progress of the metalworking industry and metallurgical manufacturing industry, this makes it possible for the winding process of the stator core to be implemented in our country. At present, a small number of domestic enterprises have begun to study and use the rolling process, but there are still many difficulties in the rolling process, and the products still have many defects. The current structural design of the winding stator core i...

[0006] 4. The warping of the tooth part; the superposition coefficient of the tooth part is unstable, the longer the tooth part is, the more unstable the superposition coefficient of the tooth part is during the lamination process, and the warping deformation is more likely to be caused; due to the inherent elastic deformation of the toothed belt material Therefore, after the lamination pressure is removed, a certain gap between the laminations will be restored, and the winding stator core usually adopts the yoke welding method, so the teeth are more likely to warp and deform, and the laminations The gap will be larger
