Abstract

A stator punching plate used for an air conditioning fan motor relates to the technical field of AC asynchronous motor modification, and is characterized by comprising an annular punching plate body, wherein the middle part of the punching plate body is provided with a hollow inner round hole and an outer circle, a punching plate groove is arranged between the outer circle of the punching plate body and the hollow inner round hole, the punching plate groove is provided with a notch, a groove shoulder, a groove body and a groove top. The stator punching plate provided by the invention has the advantages that the structure is reasonable, the flux density distribution of iron cores is effectively improved, the raw material consumption of coils and the iron cores is reduced, the energy efficiency is high and the service life is long.

Description

Technical field: [0001] The invention relates to the technical field of AC asynchronous motor transformation, in particular to a stator punching plate used for an air-conditioning fan motor. Background technique: [0002] Stator stampings for air conditioner fan motors generally include a substantially circular stamping body, a hollow inner hole is formed in the middle of the stamping body, and a uniform gap is formed between the outer circle of the stamping body and the hollow inner hole. Several punching slots extending radially are distributed. The outer diameter of the punching body of the traditional stator punching is generally 95mm, and the diameter of the hollow inner hole is generally 55 or 62mm. After magnetic circuit analysis and calculation, this stator punching structure has the following disadvantages: 1. The teeth magnetic The density tends to be saturated, but the magnetic density of the yoke is small, and the distribution of the magnetic density is uneven, ...
