B&R drive overheating

The causes and solutions for overheating of B&R drives include the following:

Check the power supply line: 

Use a multimeter to measure the power supply voltage to ensure that it is within the set value. If the power supply voltage is lower

1. Temperature Sensor Detection and Repair:

Firstly, the temperature sensor connection should be checked to see if it is normal and if the sensor is damaged. If the temperature sensor is normal, overheating faults can be detected by touching the motor housing. Under normal circumstances, the motor shell should be only slightly hot or not hot. If the motor housing is very hot or even scalding, there is a fault inside the motor.

2. Cleaning the cooling system:

If the B&R servo motor's cooling system is blocked by dust or other impurities, it will result in poor heat dissipation and thus overheating failure. Therefore, it is necessary to clean the heat dissipation system of the motor, including cleaning the heat dissipation fan and the heat dissipation channel.

3. Check the load situation:

If the B&R servo motor is overloaded for a long time, it will lead to motor overheating. Therefore, the load condition of the motor needs to be checked to ensure that the motor operates within the rated load range.

4. Replacement of Insulating Material:

If the insulating material inside the B&R servo motor is deteriorated or damaged, it can lead to a short circuit or overheating failure of the motor. At this time, you need to replace the insulating material with a new one.

5. Repair Bearing Wear:

Bearings are an important part of the B&R servo motor, if they are worn or loose, it will affect the normal operation of the motor and may lead to overheating failure. In this case, it is necessary to repair the bearing wear or replace the bearing with a new one.

6. Adjust the power supply parameters:

If the power supply parameters of B&R servo motor are not set correctly, it may lead to overheating of the motor. Therefore, it is necessary to check whether the power supply parameters are correct and adjust them accordingly.

In summary, solving B&R drive overheating problems requires a combination of several aspects, including checking and maintaining the cooling system, adjusting loads, replacing damaged parts, and ensuring power parameters are set correctly. These measures will help ensure that B&R drives operate properly and avoid overheating failures.
