High-torque waterproof motor and stator punching sheet insulation treatment process thereof

Abstract

The present invention discloses a high-torque waterproof motor and a stator punching sheet insulation treatment process thereof. The motor comprises a shell, a rotating shaft, a stator and a rotor, the stator comprises a stator punching sheet, a through hole is formed in the center of the stator punching sheet, sawteeth are evenly arranged on the circumferential side face of the through hole, a winding groove is formed between every two adjacent sawteeth, and positioning holes are evenly formed in the stator punching sheet. The technology comprises the steps of barrel body installation, paintliquid circulation system installation, primary paint dipping treatment, secondary paint dipping treatment, spin-drying treatment and drying treatment. According to the invention, the positioning holes are designed,the supporting columns are conveniently installed in the positioning holes when the stator punching sheets are subjected to paint dipping, a gap is formed between every two vertically-adjacent stator punching sheets, paint liquid can make contact with all the outer surfaces of the stator punching sheets conveniently, the insulation effect of the stator punching sheets is improved, the insulation treatment process is simple in step, and the insulation effect and quality of the stator punching sheets are greatly improved.

Description

technical field [0001] The invention relates to a high-torque waterproof motor and its stator punching insulation treatment process. Background technique [0002] During the production and processing of the motor in the prior art, the stator punching is generally insulated by the oxide film of the silicon steel sheet itself, usually without insulation treatment, so the iron core is easy to rust, which affects the service life, and the eddy current loss is large, and the temperature rise High, the motor efficiency is low; at the same time, due to the process of stator punching insulation treatment, there are defects in the surface insulation layer of the stator punching sheet, which affects the performance of the insulation between the punching sheets. Contents of the invention [0003] The purpose of the present invention is to provide a high-torque waterproof motor and a technical solution for its stator punching insulation treatment process in view of the deficiencies in...
