Here are some operations and solutions that may cause the servo motor to overheat:
1) Overload Operation: Loading the servo motor beyond its rated capacity may result in overheating. The solution is to ensure that the load is within the rated range of the servo motor and select the appropriate power and specification servo motor according to the application needs.
2) Long-term high-load operation: Continuous long-term high-load operation will cause the internal temperature of the motor to rise. The solution is to increase heat dissipation measures, such as installing cooling fans, heat sinks, or cooling systems, to improve the heat dissipation performance of the servo motor.
3) Improper ambient temperature: If the servo motor is running in a high temperature environment, its heat dissipation ability may be affected, resulting in overheating. The solution is to ensure that the servo motor operates within the appropriate ambient temperature range, or to take measures to reduce the ambient temperature, such as using cooling equipment or ventilation systems.
4) Incorrect power supply voltage: If the power supply voltage is unstable or higher than the rated voltage of the servo motor, it may cause the motor to overheat. The solution is to check whether the power supply voltage meets the requirements of the servo motor and ensure that the voltage is stable.
5) Inappropriate parameter settings: Incorrect parameter settings, such as too high speed, acceleration or too low enable frequency, may cause the servo motor to overheat. The solution is to set the parameters correctly according to the specifications and application requirements of the servo motor to avoid exceeding the capacity range of the motor.
6) Insufficient maintenance: Lack of regular cleaning, lubrication and inspection can lead to dust build-up inside the motor, increased friction or damage to parts, which in turn can lead to overheating. The solution is to carry out regular maintenance to ensure the normal operation and heat dissipation performance of the servo motor.
If the servo motor overheats, the operation should be stopped immediately and the following measures should be taken:
1) Check whether the load and environmental conditions are in line with the rated range of the servo motor.
2) Check whether the power supply voltage and parameter settings are correct.
3) Improve heat dissipation measures, such as adding cooling fans or cooling systems.
4) Carry out maintenance, clean the motor, check the windings and bearings, etc.
5) If the problem persists, you should contact the manufacturer or the relevant technical support team for further troubleshooting and solutions.
