Why does the manufacturer of automatic winding machine conduct temperature rise test on the automatic winding machine? During the inspection of our automatic winding machine and full-automatic winding machine, there is a process to conduct overspeed test on the automatic winding machine. The purpose of this test is to check the quality of our winding machine and improve its service life.
　　When the automatic winding machine is in operation, there will be iron loss and copper loss. These losses will eventually be converted into heat energy, which will raise the temperature of each part of the automatic winding machine, and the high temperature will quickly reduce the life of the insulation material. The service life of the automatic winding machine is mainly determined by the insulation aging of the automatic winding machine.
　　Therefore, a certain operating temperature is specified for various insulating materials. When the automatic winding machine is working, if the insulation material reaches the specified temperature limit, the load energy of the automatic winding machine is the maximum load, that is, the rated load.
　　If the temperature of the automatic winding machine exceeds the specified value, the service life of the winding machine will be shortened due to the rapid aging of insulation, even if the winding machine will not be burnt out immediately. At this time, the capacity of the winding machine must be reduced to reduce the load current and motor temperature.
　　To sum up, whether the rated output capacity of the winding machine meets the requirements and how large the load is shall be determined by the temperature rise test. In addition, various faults of the winding machine that we often encounter are also the cause of the excessive temperature rise of the winding machine. Therefore, the temperature rise test is a means to judge the faults of the winding machine.
