Allen-Bradley began its existence as the Compression Rheostat Company in 1903. It was founded by Lynde Bradley and Dr. Stanton Allen and the company changed its moniker to feature the founders’ names in 1909. The company flourished with the expansion of the radio industry and in supplying the military with various electronic equipment during World War I and World War II. In the Seventies and Eighties Allen-Bradley’s Industrial Automation products included numerous servo motors and other types of servo systems equipment.
The company remained privately owned until 1985 when it was purchased by Rockwell. In the Nineties Allen-Bradley was placed under the umbrella of Rockwell Automation along with Reliance Electric and its subsidiary brands Electro-Craft and Dodge whom Rockwell had acquired in 1994. In 2007 Rockwell sold its Power Systems division to Baldor meaning the Allen-Bradley, Reliance, and Dodge brands and their products are now under Baldor’s ownership.

This series of drives has a output voltage of 300 VDC. Peak current range of 30 - 90 A and between 15 - 45 A continuous output.
Sometimes having an SEM 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 SEM products. The older DC servo motors may be crossed over to newer products from SEM 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.
