A large collection of reasons for the overheating of electric hoist motors in group cranes
The group crane electric hoist is a low-speed chain electric hoist that can be synchronously lifted and lowered by multiple units, and is widely used. During use, many users may encounter the phenomenon of electric hoist motors overheating, which not only affects the normal use of electric hoists to a certain extent, but even slight carelessness can cause major safety accidents. Therefore, when encountering motor overheating, it is necessary to promptly identify the cause and handle it.
1. Check if the group crane electric hoist is overloaded during use. Overloading is one of the main causes of motor overheating. Prolonged overloading is likely to burn out the motor and cause major safety accidents.
2. Whether the motor bearing components are damaged, the allowable temperature of the outer ring of the bearing during motor operation should not exceed 95 ℃. If the temperature exceeds this value, it means that the motor bearing temperature is too high, also known as motor bearing heating. Bearing overheating is one of the most common faults in motors. Mild cases can cause the lubricating grease to dilute and leak out, while severe cases can damage the bearings.
3. Winding short circuit, turn to turn short circuit, phase to phase short circuit, and winding open circuit
4. Poor assembly of motor end covers or bearing covers.
5. The air gap between the stator and rotor of the motor is very small, resulting in collision and heating between the stator and rotor.
6. The high power supply voltage leads to an increase in excitation current, causing the motor to heat up.
7. Almost more than half of the motor burnout is caused by motor phase loss operation.
8. Abnormal vibration or noise of the motor can easily cause the motor to heat up.
If the electric hoist you are using has a motor heating phenomenon, you should immediately stop the operation and troubleshoot the above faults one by one
