The Shift from Brushed to Brushless Servo Motors in the 1990s and the Rise of Affordable DC Brush Servo Motors
In the 1990s, machine manufacturers transitioned from brushed servo motors to brushless servo motors as the cost of brushless technology dropped. Brushless servo motors offered key advantages, including higher speeds and the elimination of brush maintenance. As the demand for DC brushed servo motors declined, machine builders gradually phased out this technology. Consequently, the price and delivery times of DC brushed servo motors surged.
Potomac Electric aims to fill the gap in the machine tool industry by providing high-quality, cost-effective DC brushed servo motors. We are committed to offering affordable solutions that meet the evolving needs of our customers.
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 through our Inquiry and Quotes page with any questions.
Many of the servomotors listed above are in stock and waiting for your order so please call for details at (617) 364-0400.
