Embodiment 1

[0029] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0030] refer to figure 1 and 2 , this embodiment provides a stator core structure, which is widely used in motors, including multiple sets of stator teeth 2 arranged in a circular array, and a stator yoke 1 connecting the stator teeth 2, and the stator teeth 2 The length direction extends along the axial direction of the stator yoke 1 , wherein the length of the stator tooth 2 is the length of the stator yoke 1 . The stator yoke 1 and the stator tooth 2 are composed of a multi-piece stacked and fixed punching unit. The stator tooth unit, the stator yoke unit or only the stator yoke unit are formed on the punching unit. After stacking and fixing, the The stator teeth 1 and the stator teeth 2 are formed. Only the stator yoke unit is formed in the stamping unit present at one or both ends, so that the length of the stator yoke...

Abstract

The invention provides a stator core structure, and the structure comprises a plurality of groups of stator tooth parts which are arranged in a peripheral array, and also comprises a stator yoke partwhich enables the stator tooth parts to be connected together. The length direction of the stator tooth parts extends in the axial direction of the stator yoke part, and the length of the stator toothparts is less than the length of the stator yoke part. The structure improves the operation efficiency of a motor, is not liable to be scrapped, does not affect the heat dissipation effect and savesthe cost.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a stator core structure and a motor. Background technique [0002] The stator core is an important part of the motor, and the stator core is generally composed of a stator yoke and stator teeth formed on the inner circumference of the stator yoke. With the development of the market, the requirements for high efficiency and low energy consumption of motors are gradually increasing. In order to achieve this goal, refer to image 3 , From the perspective of motor design, reducing the stator flux density can effectively reduce the iron loss to reduce energy consumption, thereby improving the efficiency of the motor. On the premise that the outer dimensions of the motor are basically unchanged, increasing the axial length of the stator core is an effective way to effectively reduce the stator flux density. The stator core in the prior art is formed by stacking punched sheets. In order...
