subject: Looking To Get Your Allen Bradley Servo Motor Repaired? [print this page] After the motor has been analyzed, repaired and tested, it needs to be reassembled. The reassembly emphasizes the use of high quality sealed bearings to avoid contamination. In order for that to happen, it is recommended by expert repair service companies to use double lip seals and a double epoxy coating. These aspects work towards protecting the repaired motor from any possible damage.
If you are looking to get an Allen Bradley Servo motor repaired, you need a repair company that will ensure the job is perfectly done during every service. Not only do they need to return quality work but they also need to meet the factory specifications that are required for each specific model. During the repair and testing, the technician will follow several steps to ensure your Allen Bradley motor is functioning properly.
1.Evaluation of the faulty motor.
Allen Bradley Servo Motors repair services involve inspecting and testing the motor in order to find out what the problem is. This process involves:
Checking and analyzing the mechanical condition of the encoder and the pre-programmed data fields that drive the encoder.
Checking the fit of the bearings and housings in the motor.
Checking whether the output shafts and end bells are worn out.
Checking flanges to see whether they are broken or corroded.
2.Analysis of the motor.
The analysis is performed using the latest equipment by a technician who is professionally trained. After extensive analysis, the specific problem is identified so that appropriate steps can be executed to ensure that the motor is working properly.
3.Repair or remanufacture the broken part.
Depending on the conditions that are discovered in the evaluation process, the technician will decide to either repair or remanufacture the fault. Different conditions can be worked on during the repair of the Servo motor. The changes that can be made include:
Reprogramming of the Stegmann encoders or replacing it with a new one.
Using the old flange, remanufacturing can be done to factory specifications.
The windings on the motor can be washed and baked.
If the tachometer field frames are faulty on the DC motors, they can be remagnetized.
The faulty connectors can be replaced by new Allen Bradley connectors.
On AC motors, magnetic rotors can be remagnetized and rebanded.
These repairs have to be handled by an experienced Allen Bradley technician who possesses the skills necessary to perform the repairs. The replacement parts that are used need to be of high quality.
4.Testing the repaired motor.
Proper Allen Bradley Servo motors repair requires component testing to determine whether the repair has been successful. The tests that are performed include:
Testing whether there is any grounded electrical parts in the motor.
Surge testing of the potting material of stators up to 1500 volts.
Taking the armatures in a DC servo motor through a bar to bar test to show whether there are any openings or shorts in the windings.
The feedback is checked to see whether it is in alignment with the Allen Bradley drive.
5.Motor assembly
After the motor has been analyzed, repaired and tested, it needs to be reassembled. The reassembly emphasizes the use of high quality sealed bearings to avoid contamination, use of double lip seals and a double epoxy coating. These aspects work towards protecting the repaired motor from any possible damage.
6.Final testing
The Allen Bradley servo motor repair service is not complete until the motor is run on a drive that is similar to the one you use the motor in. This step will ensure that the motor is working perfectly and that the repair was successful.
Before you pick up the repaired motor, the information that was on the name plate will be put on a new one and a trace tag will be put on the motor to help with traceability. A date will also be included to help you know when the motor was last repaired.
