DEG C, second heating Control for Kiln Temperature is at 50~60 DEG C, and temperature of insulating paint≤40 DEG C；
2), cool down：The stator is naturally cooled into room temperature；
3), vacuum paint dipping：The stator is put into vacuum tank, and the air in the vacuum tank described in vacuum pumped,
Then the insulated paint is injected into the vacuum tank and pressurizeed to the insulated paint；
4), leaching paint：Need to carry out leaching paint processing after the stator vacuum paint dipping；
5), gel：The stator, which is placed on the batea of rotation, makes the insulated paint carry out even solidification, batea rotating speed
For 1~2r/min, required time 1h；
6), cure：Oven temperature is heated to 150 DEG C, then the stator is put into the baking oven and toasts 3h；
7) paint, is scraped：Taken out when the stator curing terminates and temperature drops to 65~75 DEG C in the baking oven, will be described fixed
The paint knurl in sublist face scrapes off.
Preferably, pressurizeed in the step 3 using compression pump to the insulated paint.

Contact.
Brief description of the drawings
Fig. 1 is the flow chart of motor-stator dipped lacquer technique according to embodiments of the present invention.
Embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with drawings and the specific embodiments, to this
Invention is described in further detail.
Fig. 1 is the flow chart of motor-stator dipped lacquer technique according to embodiments of the present invention.As shown in Figure 1, the present invention provides
Motor-stator dipped lacquer technique, comprise the following steps:
In step slo：Preliminary drying, stator need to carry out preliminary drying by 2 Reheating Furnace Zones, and first heating Control for Kiln Temperature exists
120~130 DEG C, second heating Control for Kiln Temperature is at 50~60 DEG C, and temperature of insulating paint≤40 DEG C, is made by high-temperature heating described
The moisture content of stator is dried completely.
In step s 11：Cooling, the stator preliminary drying make it naturally cool to room temperature, prepare for vacuum paint dipping.
In step s 12：Vacuum paint dipping, the stator is put into vacuum tank, and the vacuum tank described in vacuum pumped
In air the vacuum tank is in vacuum state, then by the insulated paint be injected into the vacuum tank and to it is described absolutely
Edge paint pressurizes.Using vacuum paint dipping mode, make dipping lacquer more thorough, uniformly, and during vacuum paint dipping paint solution taste not to extending out
Dissipate so as to reduce the pollution to environment, and the insulating properties of stator coil can also be increased.
In step s 13：Leaching paint, needs after the stator vacuum paint dipping to carry out leaching paint processing, can so make up
Existing paint solution is not thorough uniformly during vacuum paint dipping, and the mechanical strength for strengthening stator coil make stator coil be not easy it is loose, get rid of
Line, to accelerate the heat conduction velocity of stator coil and to block contact of the moisture in air with stator coil, so that further
Improve the insulation performance of the stator.
In step S14：Gel, the stator, which is placed on the batea of rotation, makes the insulated paint uniformly be coagulated
Gu batea rotating speed is 1~2r/min, required time 1h.The insulated paint under the influence of centrifugal force, the thicker region of paint solution
The relatively thin region of paint solution is transferred to, so that paint solution is more uniform, forms one layer of uniform paint film.
In step S15：Cure, oven temperature is heated to 150 DEG C, be then put into the stator in the baking oven simultaneously
Toast 3h.
In step s 16：Paint is scraped, is taken when the stator curing terminates and temperature drops to 65~75 DEG C in the baking oven
Go out, paint knurl usually occurs in the stator surface, and the paint knurl of the stator surface can influence the insulation performance of the stator, to make
The stator surface smoothly needs to be scraped off knurl is painted with special blade.
Furthermore, it is understood that pressurizeed in the step 3 using compression pump to the insulated paint, the temperature of the insulated paint
Between 55~65 DEG C and time of the vacuum paint dipping is 0.5~1h
In conclusion motor-stator dipped lacquer technique provided by the invention, carries out stator by using two Reheating Furnace Zones
Heat, and using vacuum paint dipping mode and carry out scraping paint knurl processing, motor stator surface is formed one layer of not only uniform but also light
Sliding paint film, not only improves the insulation performance of stator, but also the mechanical strength for strengthening stator coil makes stator coil be not easy pine
Dissipate, fishing line, to accelerate the heat conduction velocity of stator coil and to block contact of the moisture in air with stator coil.
The foregoing is merely the embodiment of the present invention, is not intended to limit the invention, for those skilled in the art
For member, the invention may be variously modified and varied.Any modification within the spirit and principles of the invention, being made,
Equivalent substitution, improvement etc., should be included within scope of the presently claimed invention.
