Embodiment Construction

[0017] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] figure 1 It is a flow chart of the motor stator dipping process according to the embodiment of the present invention. Such as figure 1 As shown, the motor stator dipping process provided by the invention comprises the following steps:

[0019] In step S10: pre-baking, the stator needs to pass through two heating furnace zones for pre-baking, the temperature of the first heating furnace is controlled at 120-130°C, the temperature of the second heating furnace is controlled at 50-60°C, and the temperature ≤40°C, the water content of the stator is completely dried by heating at high temperature.

[0020] In step S11: cooling, the stator is pre-baked to allow it to cool naturally to room temperature to prepare for vacuum dipping.

Abstract

The invention provides a motor stator immersion painting process. The process includes following steps: pre-drying, pre-drying a stator through two heating furnace areas, wherein the temperature of afirst heating furnace is controlled at 120-130 DEG C, the temperature of a second heating furnace is controlled at 50-60 DEG C, and the temperature of insulating varnish is lower than 40 DEG C; cooling, naturally cooling the stator to a room temperature; vacuum immersion painting, putting the stator in a vacuum tank to perform vacuum immersion paint processing; paint sprinkling, performing paint sprinkling processing after completion of vacuum immersion painting of the stator; adhesive solidification, putting the stator on a rotating painting tray to enable the insulating varnish to be uniformly solidified, wherein the rotating speed of the painting tray is 1-2 r / min, and the required time is 1h; curing, heating a baking oven to the temperature of 150 DEG C, and then putting the stator inthe baking oven and baking the stator for 3h; and paint scraping, taking the stator out of the baking over after the curing of the stator is finished and the temperature is reduced to 65-75 DEG C, andscraping paint projections on the surface of the stator. According to the process, the surface of the stator of the motor forms a uniform and smooth paint film.

Description

technical field [0001] The invention relates to the technical field of electric motors, in particular to a paint dipping process for electric motor stators. Background technique [0002] Motors are widely used in the household appliance industry, and the stator of the motor needs to be dipped in paint. The stator is impregnated with varnish to meet the technical requirements of insulation performance, so that the rotor can remain undisturbed during its rotation. The traditional stator impregnation process has defects such as incomplete impregnation and uneven paint film, resulting in lacquer spots on the surface, which may lead to short circuits between turns, and even fires and other safety accidents. Contents of the invention [0003] The invention provides a motor stator varnish dipping process to solve the problem of uneven and rough paint film on the stator in the prior art. [0004] In order to solve the problems of the technologies described above, the invention p...
