In the 1990s, the majority of machine manufacturers shifted from brushed servo motors to brushless type servo motors as cost of the technology decreased. The higher speeds and absence of brush maintenance in the brushless type 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 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 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 pressure in maintaining machinery. Please drop us a note at our Inquiry and Quotes page with any questions.
