Potomac Repair Services offers 20 years of expertise in servo motor and servo drive repairs for Bridgeport milling machines. We also manufacture and design Form, Fit, and Function replacement parts.

Contact us! We may have already solved your problem!

Potomac Electric is the industry leader in manufacturing replacement servo motors for Bridgeport CNC milling machines. Potomac Electric has developed compact, high-energy replacement servo motors for Bridgeport (now Hardinge) machines. Made in the US, they feature a durable silver commutator for superior performance. DC servo motors and servo drives have continued to be the workhorse of the CNC industry. This is why Potomac Electric has invested in designing a new line of DC servo motors to support industry needs. Potomac Electric's excellent technical support and experienced engineers will ensure that every customer will benefit from upgrading to Potomac Electric servo motors.

Among the servo motors you find on your Bridgeport CNC milling machines and machining centers are motors from companies such as SEM, CMC Torque Systems, Powertron, Contraves, and a few others. Potomac Electric makes replacement servo motors for all of the brands.

In the 1990s, the majority of machine manufacturers shifted from brushed servo motors to brushless servo motors as the cost of brushless technology had decreased. The higher speeds and absence of brush maintenance in brushless servo motors offered favorable advantages. As DC brush-type servo motors became less attractive, machine builders slowly phased out this technology. As a result, the price and delivery of the DC brush servo motors increased dramatically. Potomac Electric has set a goal to fill such a void in the machine tool industry with high-quality DC brush servo motors at a low cost.

The list of servo motors we support is constantly growing as we identify the needs of our customers. We are a small business and we understand the difficulty and cost of maintaining machinery. Feel free to reach out with any questions through our Inquiry and Quotes.

Many of the servomotors listed above are in stock and waiting for your order, so please call for details at (617) 364-0400. Servomotor models that do not appear in this list may be in our Parts Inventory, so contact us with any inquiries for small lot production.
