Problems solved by technology

At present, the insulation varnish baking process mostly adopts one-time heat treatment and baking, which is easy to cause incomplete heat treatment, poor baking effect, and weak adhesion of the paint layer.
Baking treatment is carried out in a rotating manner. Due to the gravity and centripetal force of the stator, a large amount of paint impregnated in the lower part of the stator will be lost, resulting in uneven paint hanging on the upper and lower parts of the stator, and a small amount of paint hanging on the upper part, which will affect the effect of insulating paint dipping.

Abstract

The invention discloses a paint dipping technology for an AC stator of a fan motor. The paint dipping technology includes steps of (1) paint dripping; (2) mixed paint preparation; (3) pre-drying; (4) paint dipping; (5) drying; (6) process ending. By adopting the paint dipping technology provided by the invention, thorough paint dipping is ensured and insulation effect of the AC stator of the fan motor is improved, and moisture resistance, heat resistance, electric conduction performance, magnetic conduction performance and mechanical performance of the AC stator of the fan motor are ensured.

Description

technical field [0001] The invention relates to the technical field of paint dipping, in particular to a paint dipping process for an AC stator of a fan motor. Background technique [0002] The insulation dipping treatment of the AC stator of the motor is a very important link in the manufacturing process of the motor stator, which is directly related to the service life of the motor. In the treatment process of insulating varnish, there are generally two methods: one is to stand the stator of the motor in the baking room and bake it in a static state; the other is to bake it in a rotating manner. After the motor stator is dipped in varnish, it is baked in a rotary baking method. The winding insulation varnish has good filling properties, less paint loss during the baking process, and even varnish on the surface of the winding. It has been widely used. At present, the baking process of insulating varnish mostly adopts one-time heat treatment and baking, which may easily cau...
