Method for electrify and heating motor win

In the process of manufacturing and repairing the motor, it is necessary to wrap the motor winding and immerse it in the paint cylinder, which is used to fill the gap between the motor windings, solidify the winding and the iron core, and achieve the purpose of electrical and gas insulation. The paint dipping process of motor winding is to immerse the motor core and winding into the paint barrel as a whole, and finish the paint dipping of motor winding through multiple processes such as soaking, dripping paint, heating, curing and cooling. This process takes a long time, has extremely low efficiency and high cost, and is completely filled with liquid paint flowing into the gap of the motor winding during the paint dipping process, so there are inevitably holes or bubbles in the gap of the motor winding, which affects the paint dipping quality of the motor winding and reduces the insulation performance of the motor winding.

The technical problem to be solved by the invention is to provide an electric heating paint dipping method for motor windings. This method significantly improves the efficiency of motor winding impregnation, reduces the time and cost of impregnation, and improves the quality and insulation performance of motor winding impregnation.

In order to solve the above technical problems, the electric heating paint dipping method for motor windings comprises a heating power supply with adjustable frequency and current, a curing box with an ultraviolet lamp set and a paint dipping cylinder, wherein the frequency of the heating power supply can be

The modulation range is 0-500HZ, and the current adjustable range is 0-400 A..

Step 1, test the electrical performance of the wound motor winding to ensure the winding of the motor winding.

Correct and good electrical performance, the motor winding is placed in the curing box;

Step 2, connect the two ends of the motor winding to the heating power supply, and set the heating power supply according to the parameters of the motor.

Heat the frequency and current of the power supply, and start the heating power supply to heat the motor winding to 100- 18(TC, when heating.

3 rooms for 8- 10 minutes;

Step 3, move the motor winding into the paint dipping tank and immerse it in the paint dipping tank for 8- 10 minutes;

Step 4, taking the motor winding out of the paint dipping tank and dripping paint on the motor winding for 4-6 minutes;
