Fully Automatical Stator Heat Treatment Oven Coated With Resin Varnish WIND-ZCJ






Stator varnish machine composed of machine body, water cooler and varnish supply tank. It is mainly


applied to stator winding insulation treatment for fractional horsepower motor and industrial Y series motor


which is below frame size 132.



Dipping time depends on varnish density


Water pump dipping time usually is 2 minutes , and few minutes per cycle


1. Clean up the frame

Clean the paint on the frame and other impurities, and apply anti-sticking measures to the frame, such as


brush grease.



2. Load on Stator

There should be no dust or other debris on the stator. It must be removed before dipping. The stator is


placed neatly in the frame according to a certain distance. Generally, the stator should be placed


vertically in the frame. Some lead wires have problems such as hardening after drying and poor


conductivity. Therefore, the lead wires are generally bundled and then lifted up to avoid impregnation


before dipping.



3. Preheat

Generally, the preheating section temperature is set to 110-150° C. After the stator undergoes preheating


for 10-30 minutes, the surface temperature reaches about 90 degrees, and the steam in the core and the


coil can be removed. On the other hand, the insulating paint after preheating can be used. Quickly


penetrates into the coil and iron core. From the profile of the continuous immersing machine, it can be


seen that the preheating section is in fact connected to the upper curing section. Therefore, when a


water-soluble insulating paint is used, although the water-soluble insulating paint may not be pre-baked,


the heater of the preheating section cannot be turned off and the temperature setting should be


consistent with the curing section for easy penetration and efficient use of the curing time.


4. Cooling

After the stator passes out of the preheating section, the temperature is not uniform, and the local


temperature is too high. If the high-temperature workpiece directly enters the oil-soluble insulating paint,


the solvent will evaporate rapidly and cause a safety accident. In addition, when the insulation paint is in a


high temperature state for a long time, the probation period is drastically reduced, and an increase in


viscosity or even an overall gel is liable to occur and the pipe is clogged. Therefore, it is necessary to go


through a brief cooling to reduce the stator temperature to about 70 degrees.


5. Dipping

The sloping frame is completely immersed in the lacquer. The immersion lacquer time is generally


controlled between 30-80 s. It is adjusted according to the size and structure of the stator. The flow rate of


the dipping paint should be adjusted to ensure that the dipping tank is full of paint.



6. Solidification

After the lacquer work is completed, the workpiece enters the drying tunnel with the driving device to


complete the curing process. Depending on the size of the workpiece, it usually takes 1-3 hours.

We produce stator varnish machine in electricity power,diesel power or gas, It has two types mechanism in
the varnish area:
1. Varnish tank goes up and down which is driven by the screw rod
2. Varnish tank fixed and the chain goes down and up
Situation 1 is suitable for stator with dipping time requirement, suppose the varnish dippin time is 2
minutes and pitch time is 5 minutes, stator don't need to stay inside the varnish tank for 5 minutes

In situation 2, the varnish tank don't move and don't need transmission, no drive needed,


Stator varnish machine which mainly applied to stator winding insulation treatmen composed of machine


body, water cooler chiller and varnish supply tank.


Electric insulating Impregnating resins and varnishes, potting compounds, conformal coatings, varnish and paint for industries.

There are different insulation stage related to electric motor insulation.

1. Electrostatic powder coating

2. Slot insulation (Insert insulation paper polyester to armature or stator slots)

3. Wedge insertion

4. Impregnation varnish dipping or trickling

Good quality epoxy resin offers a broad range of impregnation resin for motors, generators and transformers. Optimal dipping or trickle results are granted due to our easy operation and maintance machine. The use of vacuum or vacuum pressure impregnation applications techniques provides for optimum machine protection against all type of stress by using a correctly engineered combination of impregnating resin , insulation system and application process. The removal of the air content from a winding by the application of vacuum let extend the working life of the machine due to increase of thermal dissipation as well as providing for improve mechanical properties.The use of both vacuum and pressure as a method of applying secondary insulation epoxy resin permits the application of liquid material (the liquid vanish have a wide range of viscosity, sometimes peristaltic pump is needed) to more demanding electrical equipment. The correct use of vacuum pressure impregnation also allows global impregnation for rotating electrical machines with the correctly designed insulation system up to at least 13,8 kV specifications.
