When the motor is running under load, we all hope to play its role as much as possible, and the larger the load, that is, the larger the output power, the better; But the higher the output power, the higher the loss power, the higher the temperature. Here is a simple understanding of the temperature rise of three-phase asynchronous motors with Senli Motor Xiaobian.

       In the manufacture of motors, the weakest thing to withstand temperature is the insulating material, such as enamelled wire. There is a limit to the temperature resistance of insulating materials, within this limit, the physical, chemical, mechanical, electrical and other aspects of the insulation material are very stable, and its working life is generally about 20 This year.

        Once this limit is exceeded, the life of the insulation material will be dramatically shortened, and even burn. This temperature limit is called the allowable temperature of the insulation material. The allowable temperature of the insulation material is the allowable temperature of the motor; The life of the insulating material is generally the life of the motor

       Generally, if the measuring machine cover temperature exceeds the ambient temperature 25 °If so, thenThree-phase asynchronous motorThe temperature rise has exceeded the normal range. For example, some motor manufacturers use enamelled wire temperatures higher than150°Left and right will cause the paint film to fall off because the temperature is too high, resulting in a short circuit of the coil.
