In the 1990s the majority of machine manufacturers shifted from brushed servo motors to brushless type servo motors, as 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 type servo motors became less attractive machine builders slowly phased out this technology. As a result the price and delivery of the servo motors increased dramatically. Potomac Electric set a goal to support the machine tool industry maintenance costs low with a high quality products 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. We understand the difficulty and cost pressure in maintaining the machinery in this difficult economic environment.
