Temperature rise affects the service life and operation performance of the motor, which is a very key performance index. The factors affecting the temperature rise of three-phase asynchronous motor, in addition to the design parameter selection itself, there will be many factors in the manufacturing process to cause the temperature rise does not meet the requirements of safe operation.

       To know whether the temperature rise meets the requirements, we usually take the motor thermal stability temperature rise experiment, because the simple detection is impossible to find the temperature rise problem, for exampleThree-phase asynchronous motorThe fan selection is not suitable, the thermal conductivity component is not suitable, etc., have a greater impact on the temperature rise, so it is not a single factor, there are many temperature rises caused by dipping factors, usually we will take the way of dipping paint again to remedy.

       Generally, it is recommended to consider dipping paint with the frame, which can fill the gap between the mating surfaces and avoid the possible factors that hurt the motor winding during the manufacturing process. While strengthening the insulation performance of the winding, it has a certain improvement effect on the temperature rise control of the three-phase asynchronous motor.
