Servo Repair International, Inc. repairs and replaces many of the brands of servo motors, including Porter/Peerless/Winsmith.

Peerless Electric was founded in 1893 in Warren, Ohio. Henry Porter founded H.K. Porter & company in Pittsburgh, Pennsylvannia after splitting with his prior partner John Smith following a fire in their locomotive shop. Porter was acquired by Thomas Mellon Evans in 1939 which in turn acquired Peerless Electric. In 1989 HBD Industries was founded and acquired numerous holdings to include Peerless and Winsmith from H. K. Porter.

Replacement Capabilities

 
 

Occasionally having an Porter / Peerless / Winsmith 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 Porter / Peerless / Winsmith products. The older DC servo motors may be crossed over to newer products from Porter / Peerless / Winsmith 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.
