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](http://www.bpt.com/) (now [Hardinge](http://www.hardinge.com/)) 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](http://www.bpt.com/) CNC milling machines and machining centers are motors from companies such as [SEM](https://www.potomacelectric.com/repairs/aftermarket-replacements/brands/97-sem), [CMC Torque Systems](https://www.potomacelectric.com/repairs/aftermarket-replacements/brands/78-cmc-torque-systems), [Powertron](https://www.potomacelectric.com/repairs/aftermarket-replacements/brands/102-powertron), [Contraves](https://www.potomacelectric.com/repairs/aftermarket-replacements/brands/80-csr-contraves), and a few others.

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.
