Replacement Capabilities


 
 

Occasionally having an Contraves/CMC DC 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 Contraves/CMC products. The older DC servo motors may be crossed over to newer products from Contraves/CMC 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.
