Westamp Servo Amplifiers and Motors

Potomac Electric engineers designed several Westamp products. We support servo drives and servomotor repairs.

We also design and manufacture a number of Form, Fit, and Function replacements. This saves a lot of money on machine maintenance and avoids costly retrofits.

Potomac Electric has been helping customers with Westamp products since 1992. This comes as no surprise since some of our design engineers left Westamp and came to work for Potomac Electric. After Westamp closed its doors in the late 1990s, Potomac Electric became the only authorized repair facility for Westamp products in the world.

In the late 60s, Westamp was one of the first servo drive companies to pioneer low-cost, open chassis, multi-axis products. The products were a great success due to their high reliability and low cost. Hundreds of thousands of axes were sold, especially in the machine tool industry. Boston Digital, Anilam, Gardner Grinder, Thermwood, and Globe Winders are just a few companies that used Westamp products.

The success of Westamp was not overlooked by the competition, and several other companies offered similar products. Among them were Servodynamics, Glentek, Unidrive, Baldor, EG & G Torque Systems, CSR Contraves, as well as many others.

For over 30 years, Westamp produced many generations of its product line. You may have some of these in your automation equipment: A66X, A651, A652, A653, A711, A721, A722, or A733, as well as a few brushless products. Potomac Electric has designed and manufactured direct replacements for some of the models. We have also done thousands of repairs.

Potomac Electric also offers repairs and direct replacements for all servo motors that Westamp sold.

Our repair personnel are factory trained and have extensive repair experience with the entire Westamp product line. Our repair process consists of a thorough and detailed evaluation, contacting the customer (if necessary), troubleshooting and repair, complete testing according to the Westamp specifications, and at least an eight-hour burn-in. All the test data is recorded for future reference and in conformance with ISO standards. Our regular repair service takes 2-3 weeks. Rush service is available.

We pride ourselves on quality repairs and customer service. Call Potomac Electric at 617-364-0400 when in need of repairing Westamp, Glentek, EG & G Torque (CMC), Servodynamics, and other drives.

We are a small business and we understand the difficulty and cost of maintaining the machinery. Please drop us a note on our Inquiry and Quotes page with any questions.

Many of the Westamp servo drives may be in our Parts Inventory, so contact us with any inquiries for small lot production.
