Embodiment Construction

[0023] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the embodiments and accompanying drawings, and the contents mentioned in the implementation modes are not intended to limit the present invention.

[0024] A method for impregnating and curing motor stators, taking a three-phase motor as an example, such as figure 1 shown, including:

[0025] First connect the power line to the stator, you can use such as figure 2 Y-connection method as shown or use as image 3 The △-type wiring method shown, and check whether the stator winding and the stator lead wire and the AC equipment are connected normally. If the wiring is normal, start the AC equipment to preheat the stator winding with AC power, and check whether the winding temperature reaches the set temperature of the stator winding; At the same time, heat the insulating varnish to check whether the temperature of the insulating ...

Abstract

The invention relates to the technical field of motor manufacturing, in particular to a method for paint dipping and curing of a motor stator, which comprises the following steps: preheating the stator winding with alternating current, and detecting whether the winding temperature reaches the temperature set by the stator winding; heating the insulating paint and detecting whether the temperatureof the insulating paint reaches the temperature set by the insulating paint; When the stator winding and the insulating varnish reach the set temperature, the stator is immersed in the insulating varnish, and the insulating varnish is kept constant temperature; The stator winding is continuously energized and heated to the temperature of insulating paint gelatinization, and the stator winding is kept constant temperature for a certain time; Remove the stator to drip paint and solidify the insulating paint. As that stator and the insulate paint are respectively heated to a certain temperature,the stator is put into the insulate paint, the stator is continuously heated and the insulating paint is subjected to constant temperature, so that the stator dip paint is more sufficient, the insulation strength of the motor stator is improved, and the curing hardness and the thermal conductivity of the winding are increased.

Description

technical field [0001] The invention relates to the technical field of motor production, and specifically discloses a method for dipping and curing a motor stator. Background technique [0002] In order to improve the insulation performance and enhance the heat dissipation capacity of the motor, the stator is usually dipped in varnish after the wire embedding is completed. The quality of the varnish will have a certain impact on the performance of the motor. The common varnish dipping process is to preheat the stator with windings, then immerse it in insulating varnish for a period of time, let the insulating varnish drip naturally after taking it out, and put the product in the oven to bake when there is little insulating varnish dripping. Allow the varnish to fully cure. In this way, a relatively large part of the insulating varnish will flow away, resulting in poor winding insulation treatment and curing effects, requiring multiple varnish immersions, resulting in low ef...
