Temperature rise is an important index of the motor in the design operation, marking the degree of heat of the motor, whenThree-phase asynchronous motorHeat and heat dissipation are equal, and when an equilibrium state is reached, the temperature no longer rises but stabilizes at a level; However, if the heat of the asynchronous motor increases but the heat dissipation decreases, the balance between the two will be destroyed, and the temperature will rise.
inThree-phase asynchronous motorWhen the peak operating temperature or temperature rise exceeds the specified value or does not exceed the specified value, but the temperature rise suddenly increases under low load, then the motor is faulty. For example, under the rated load, the temperature rise does not exceed the temperature rise limit, only the ambient temperature exceeds40℃However, the motor does not exceed the peak operating temperature, in this case the motor itself is normal, can make the ambient temperature drop solution, if not, it is necessary to reduce the load operation.
If the temperature rise under the rated load exceeds the nameplate provisions, no matter what the case, it can be classified as a motor fault, which should be stopped for inspection, especially the sudden increase in temperature rise needs special attention.
The main causes of motor overheating are phase missing operation, overload operation, winding wiring errors, or frequent start-up, heat dissipation duct obstruction resulting in poor ventilation, excessive ambient temperature, poor cooling effect and other reasons.
