How to improve the temperature rise of servo motor

We have previously introduced the common types of interference in servo motor applications. It can be seen that the common interferences are as follows: radiated interference, conducted interference and interference within the system. These interference problems will not have a big impact and can be solved as long as timely countermeasures are taken. So how to improve the temperature rise problem of the servo motor? Next, please see the improvement methods below!

Regarding the temperature rise of the servo motor, we can make corresponding inspections and confirmations according to the following steps:

1. Is it used for continuous operation? The characteristics of the servo motor are not suitable for use in continuous operation. In this case, a higher temperature rise will occur. Therefore, please reconfirm the mechanism operation requirements and re-evaluate the motor used.

2. Please confirm the frequency and cycle of the mechanism's actions. If the frequency of stop-and-go operation is too high, the current may be reactivated before it drops due to the pulse input stopping time being too short, so the temperature rise at this time will be high. It is recommended that you reduce the frequency of operations to improve the temperature rise problem.

3. Can the situation be improved by reducing the RUN current? When the torque is sufficient, reducing the RUN current of the driver can effectively reduce the temperature rise. However, if a larger current is used due to torque, it is recommended that you replace the motor with a larger motor and then lower the current to improve the temperature rise problem.

4. Can the situation be improved by reducing the STOP current? If the holding force is sufficient, we can reduce the STOP current of the driver to effectively reduce the temperature rise when the motor stops. However, if a larger STOP current must be used due to the stop holding force, it is recommended that you replace the motor with a larger one and then lower the current to improve the temperature rise problem.

5. What is the surrounding ambient temperature? Is it too high? Motor temperature = ambient temperature + motor temperature rise, so when the ambient temperature is higher, the temperature of the motor will also be higher. Therefore, it is recommended to install a cooling panel or cooling fan to help dissipate heat.

6. Please confirm whether the wiring at the servo motor end is correct? Wrong phase connection will cause the motor to run smoothly and vibrate, and may also cause higher temperature rise.

If there are no problems due to the above reasons, the temperature of the motor should be normal and no overheating occurs. At this time, please directly measure the real temperature of the motor with a thermometer. As for the driver, because it has an overheating protection function, if the temperature is too high, the protection function will be turned on and the servo motor will be powered off, allowing customers to use it with more peace of mind.
