Siemens is a German engineering corporation and is the largest such company in Europe. Siemens’ industrial automation division is the most profitable of the various activities of the company.

Free Motor Evaluation and Quote


Servo Repair International offers free evaluation of servo motors. Our evaluations entail a full disassembly of the unit and complete testing of all its components. The evaluation is free as a result of our four decades of engineering design, test and repair experience of servo systems. This knowledge enables us to effectively test and diagnose servo motors in an efficient time frame. In addition, by analyzing the type of failure, we may be able to identify the causative source and offer advice on preventing future failures.


Replacement Capabilities


Sometimes having a Siemens servo motor repaired is not the best option.

Extensive motor damage or unacceptable lead times, may make replacement options a more intelligent and economical choice. Servo Repair International provides various replacement options for many Siemens products. The older DC servo motors may be crossed over to newer products from Siemens or other competing manufacturers. We can also provide our own direct replacement DC servo motors as replacements. Many times just a simple feedback device crossover may be needed to increase turnaround time and better performance.
