1. Power supply failure
It's common for power supply problems to cause the geared motor to overheat. What kind of problem might it be? Check if the three phases are unbalanced and if the voltage fluctuation is greater than or less than 10%. Otherwise, unbalanced three-phase current will be generated, increasing motor losses and causing the motor to overheat.
2. Motor overload
Excessive load or motor rubbing against the rotor can cause the three-phase current to exceed the rated value, resulting in overheating of the geared motor. It is important to pay attention to the load on the motor and understand the condition of the geared motor.
3. Operation with a single phase
If a geared motor operates with a single phase, you should first find the cause. If you are unsure, you should consult a professional. Do not attempt to solve the problem yourself. If it is a minor issue, you can resolve it yourself.
4. Winding fault
A multi-winding transformer is a transformer with one primary winding and several secondary windings wound around an iron core. The number of turns in each secondary winding is different, resulting in different terminal voltages. Therefore, a multi-winding transformer can supply power to several electrical devices with different voltages. The most commonly used type in power systems is the three-winding transformer. Using a single three-winding transformer to connect three different voltage transmission systems is more economical, requires less space, and is easier to maintain and manage than using two ordinary transformers. When a winding fault occurs, it must be repaired promptly.
5. Blocked cooling airflow
If the cooling air path is blocked, the geared motor will overheat. Therefore, the cooling air path should be repaired in time to avoid such a situation.
In summary, overheating of a geared motor is generally caused by the following reasons: power supply failure, motor overload, single-phase operation, winding failure, or blockage of the cooling airflow.
