Problems solved by technology

[0004] Although this method of dipping paint twice can make the motor stator assembly achieve the effect of insulation and curing, but the consumption of insulating paint is large, the process of dipping paint takes a long time, and the power consumption is relatively high

Embodiment

[0026] The specific steps for the insulation treatment of a certain type of alternator stator assembly are as follows:

[0027] (1) Prepare an insulating varnish solution with a viscosity of 20°C, BZ-4, 29-31s, and add it to the varnish container of the immersion furnace;

[0028] (2) Install the motor stator on the mechanical claw of the paint dipping furnace to rotate, then preheat, keep the temperature at 130°C, and keep it warm for 1min;

[0029] (3) Cool down, the time is 40s, and the temperature drops to 70°C;

[0030] (4) Drip the insulating varnish solution to the part of the rotating stator coil to be dipped through the dripping pipe of the dipping furnace for 1.2 minutes;

[0031] (5) Heating and ventilating in the paint dipping furnace, and drying the stator assembly dipped in paint;

[0032] (6) Take out inspection: the permeability of the stator is good, and the quality is qualified.

Abstract

The invention relates to an insulating method for a motor stator. The method comprises the following steps of: preparation of an insulating varnish solution, preheating, temperature reduction, varnish impregnation, drying and the like. According to the method, the conventional twice varnish impregnation method for a motor stator component is changed, and the conventional twice varnish dripping treatment is changed into once varnish impregnation treatment by changing the viscosity of insulating varnish, so that a production cycle is shortened, and the consumption of the insulating varnish is reduced; and moreover, the preparation of two kinds of insulating varnish with different viscosities are not required, so that production management is simplified, the volume of a tunnel kiln is reduced, a space is saved, and energy sources are effectively saved.

Description

technical field [0001] The invention relates to an insulation treatment technology, in particular to an insulation treatment method for a motor stator assembly. Background technique [0002] The motor is an electromagnetic mechanical device for electromechanical energy conversion or signal conversion. During the production process of its stator assembly, insulation treatment is required. At present, my country's small and medium-sized motor manufacturers generally use the two-time dipping method. [0003] After the stator assembly is preheated, when the temperature drops to 60-80°C, dip paint once. In order to better fill the insulating paint into the inside of the stator winding, the viscosity of the paint is low. Generally, it is selected at 20°C, BZ- 4. About 18-22s, it takes a little longer, and the paint dripping time is about 3 minutes. Immediately after that, the second immersion paint is carried out, the purpose is to form a better paint film on the surface of the ...
