As a short-circuit single turn secondary coil, the motor shell is heated by the eddy current generated in the high current motor shell itself under the condition of low AC voltage. The heating purpose is achieved by relying on the energy of these eddy currents, so a lot of heat is generated. The motor shell heater itself and the yoke maintain normal temperature, but it is different from the bearing heater, especially the aluminum motor shell. It has the characteristics of fast heat dissipation, thin shell, and aluminum material is not easy to be heated. Therefore, the motor shell heater can quickly heat the aluminum motor shell and water pump shell, and the shell circumference can be heated and expanded by the same amount. It meets the assembly with the stator interference heat jacket, and has the advantages of fast heating, time saving and power saving, convenient operation, etc.
Generally, attention should be paid to the maintenance of the motor: keep the engine clean and free of dust; Regularly check the appearance of the motor to see if there is any misplaced part; Always check the bearing replacement or gas, and also check the incoming connecting thread.
The motor is one of the indispensable equipment in production and manufacturing. In order to ensure the normal operation of the motor, in addition to normal use according to the operating procedures and normal monitoring and maintenance during operation, regular inspection should also be carried out to do a good job in motor maintenance. Whether our mechanical equipment can work normally depends on whether the motor can operate normally. Therefore, motor maintenance is also very important. Many people always don't pay attention to maintenance or don't know how to maintain it. When there is a problem with the motor, the motor can only be repaired. If it is repaired, it will cost money and delay work.
