Motors play an important role in various industrial and commercial fields. Whether in the manufacturing industry, the process industry, or the air conditioning systems of office buildings, they all rely on the stable operation of motors. Among various electrical loads, motors are the single type of equipment with the largest power consumption. The abnormal heating and shutdown of motors will directly affect factory production and may even lead to serious consequences and economic losses. Paying attention to daily operation and maintenance can ensure the safe and reliable operation of motors and control systems and improve the efficiency of factories!

1. Motor overload. When the motor is overloaded, the heat generation exceeds the heat dissipation, resulting in abnormal temperature.
2. Environmental problems. In case of poor ventilation, high ambient temperature, or direct sunlight, the motor cannot dissipate heat effectively.
3. Bearing problems. Insufficient lubrication, wear, or damage of the bearings will generate frictional heat.
4. Power supply problems. Excessively high voltage or unbalanced voltage will cause the motor to overheat. Moreover, unbalanced voltage will lead to unbalanced current, exacerbating the abnormal temperature.
5. Insulation damage, which may lead to short circuits or electric leakage and generate additional heat.
6. Improper installation. When the coupling between the motor and the driving equipment is improperly installed, the motor will bear additional mechanical loads, causing the temperature to rise.
7. Winding damage. The damage of the motor windings, especially short circuits, will lead to a sudden increase in current and abnormal temperature.
