Problems solved by technology

Taking the single-phase asynchronous motor as an example, the number of slots of the traditional stator punching is mostly a multiple of 6. The advantage of this setting is that the stator punching can be used in both single-phase and three-phase motors, which brings certain convenience to production and management. This arrangement makes the utilization rate of silicon steel sheet low, and the consumption of winding copper wire is large, the cost is high, and the benefit is low, which cannot meet the requirements of saving and reducing in the new situation

Embodiment Construction

[0024] Such as figure 1 and figure 2 The structure of the motor stator punching sheet of the present invention shown in the figure is that the stator punching sheet is provided with winding slots 1 evenly arranged in phases with spaced teeth 2 along the circumference, and the area between the winding slot 1 and the outer periphery of the stator punching sheet is the stator punching sheet. The yoke of the sheet 3. The number of winding slots 1 is at least an odd multiple starting from 5 times of 4, but excluding common multiples of 4 and 6. Taking the number of winding slots 1 as a multiple of 5 of 20, and the outer diameter of the stator punching sheet as φ138mm as an example, the axis of the adjacent winding slot 1 and the angle α between the center point of the stator punching sheet is 18°, and the yoke 3 The length h1 is about 17mm, and the tooth width h2 is about 3.7mm, both of which are larger than the parameters of the traditional stator punch. Taking the YL series t...

Abstract

The invention relates to a motor stator punching plate. Winding slots are alternately formed in the stator punching plate through space teeth along the circumference, and the number of the winding slots is the odd times of four (starting from the five times of four), but does not include the common multiples of four and six. The motor stator punching plate can meet a variety of industry standards, the use ratio of silicon steel sheets is greatly increased, and the consumption of copper wires is significantly reduced. Therefore, the production cost is greatly reduced, and the requirements of material saving and consumption reducing are achieved.

Description

technical field [0001] The invention relates to a stator punch of a motor, and is particularly suitable for but not limited to a stator punch of a single-phase asynchronous motor. Background technique [0002] With the rapid development of my country's economy, the consumption of non-renewable resources such as coal, oil and natural gas, as well as electricity and various raw materials has been increasing day by day, and my country's copper materials are relatively scarce, and iron ore resources need to be imported in large quantities. In this situation, it is particularly important to save raw materials and reduce consumption to improve economic and social benefits. Taking the single-phase asynchronous motor as an example, the number of slots of the traditional stator punching is mostly a multiple of 6. The advantage of this setting is that the stator punching can be used in both single-phase and three-phase motors, which brings certain convenience to production and managem...
