Stator

Abstract

A stator comprises a plurality of first tooth parts and yoke parts which are mounted on the first tooth parts respectively. each first tooth part is of a split type structure and comprises a plurality of bent teeth and a plurality of straight teeth, wherein the bent teeth and the straight teeth are arranged alternatively and form a circle, a central hole is formed in the center of the circle, and a through groove, through which the central hole is communicated with the yoke parts, is formed between adjacent bent tooth and straight tooth. Compared with the prior art, the stator has the advantages that by means of the through grooves arranged on the teeth parts, the working performance of the stator is improved, and by means of the split type structure of the tooth parts and the yoke parts, the stator is simple in structure and convenient to assemble.

Description

【Technical field】 [0001] The invention relates to a stator, in particular to a stator for a single-phase motor. 【Background technique】 [0002] In the single-phase motor of the prior art, the stator of the single-phase motor usually adopts the method of distributed winding to wind the iron core, such as figure 1 As shown, both sides of the coils of the first winding 91 and the second winding 92 of the winding all span a certain number of stator slots, then the first and second windings 91 and 92 have two stator slots 931, 932 that span simultaneously, The two stator slots 931, 932 also need to be wound with other coils. In order to meet the requirements of the first winding 91 and the second winding 92, the two sets of coils must have enough avoidance space in the iron core to wind other coils. It is required that the length of the first winding 91 and the second winding 92 protruding from the iron core should be sufficient, that is, the length of the end of the coil should...

AI Technical Summary

Problems solved by technology

For the motor, the winding at the end not only consumes copper, but also consumes electric energy, which affects the efficiency of the motor

On the other hand, since the coils at the ends protrude longer, in order to fix the coils at the ends, they need to be bound manually, which greatly reduces the degree of automation and lower production efficiency

[0003] In addition, on April 2, 1993, Japanese Patent Application Laid-Open No. 5-83907 disclosed a stator for a single-phase motor, which is composed of a number of laminated silicon chips, each of which has an integrated structure , which includes a circular bridge 16 and a number of teeth 14 connected to the bridge, the teeth are evenly distributed on the outer ring of the bridge, a number of slots 15 are formed between the teeth, and the windings are wound inward from the periphery of the stator. As a result, the traditional winding method from the inside of the stator to the outside has been changed. The effect of the stator is: it can reduce the protruding length of the winding at the end of the stator, increase the degree of automation of winding, and improve the utilization rate of copper wires. However, such a design , the working performance of its motor is not maximized
