In the process of Rexroth servo motor maintenance, brake failure is a common fault. In order to deal with this problem effectively, maintenance personnel need to master some common maintenance methods. The following will introduce the principles, implementation steps and precautions of these methods in detail to help maintenance personnel better solve the fault of brake failure.
First of all, maintenance personnel need to understand the possible causes of brake failure, such as brake pad wear, brake coil damage, brake circuit failure, etc. For these reasons, maintenance personnel can take the following common methods for repairs:
1. Replace the brake pads.
When brake pads are badly worn, it can cause brakes to fail. At this time, the maintenance personnel need to replace the brake pads in time. During the replacement process, the service personnel need to select the appropriate brake pad model to ensure that it matches the motor model. At the same time, when installing brake pads, maintenance personnel need to pay attention to the gap between the brake pads and the brake disc to avoid too large or too small clearance resulting in poor braking effect.
2. Check the brake coil.
Brake coil damage is also a common cause of brake failure. Maintenance personnel can judge whether it is damaged by checking the resistance value of the brake coil, insulation performance, etc. If the brake coil is damaged, the maintenance personnel need to replace the brake coil with a new one in time to ensure that the motor brake function is normal.
3. Check the fault of the brake circuit.
Brake failure can also result in brake failure due to faulty brake circuitry. Maintenance personnel need to conduct a comprehensive inspection of the brake circuit, including circuit connections, circuit components, etc. During the troubleshooting process, maintenance personnel need to use tools such as multimeters to detect the performance of circuit components, find fault points and repair them.
In short, when repairing Rexroth servo motor brake failure, maintenance personnel need to master the above common methods and apply them flexibly according to the actual situation. At the same time, maintenance personnel also need to pay attention to the safety issues in the maintenance process to ensure that the maintenance process will not cause secondary damage to the motor.
