Working on Hardinge servo motors for many years, Potomac Electric has developed new high-energy replacement servo motors. Engineered and manufactured in the USA, these new servo motors feature a compact size, high quality, and a new silver commutator.

In the 1990s, the majority of machine manufacturers shifted from brushed servo motors to brushless servo motors as the cost of the technology had come down. The higher speeds and absence of brush maintenance in the brushless type servo motors offered favorable advantages. As DC brush servo motors became less attractive, machine builders slowly phased out this technology. As a result, the price and delivery of these servo motors increased dramatically. Potomac Electric has set a goal to support such a void in the machine tool industry with a 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 the machinery. Please drop us a note on our Inquiry and Quotes page with any questions.

Many of the Hardinge servo motors and drives may be available in our Parts Inventory, so  please contact us if you have any small-lot production needs.
