Aftermarket Replacements
For over 20 years, Potomac Electric has specialized in repairing and remanufacturing servo motors, pumps, actuators, servo drives, spindles, and motion controllers for industrial and military applications. Leveraging our extensive experience with specific machines and applications, we also design and manufacture high-quality aftermarket replacement components and complete retrofit systems. Our Form, Fit, and Function replacements ensure seamless integration—allowing us to replace outdated motors, drives, and cables with precision-engineered solutions that mechanically fit the same way and flawlessly interface with existing CNC, PLC, and motion control systems. By minimizing downtime, our solutions help customers significantly reduce costs and maintain peak operational efficiency.
We provide field assistance when needed, but in most cases, customers easily install our retrofit solutions themselves—that’s how seamlessly they are designed! OEMs and machine builders rely on our retrofits to support aging systems when original parts become unavailable or too costly. End users benefit just as much, ensuring continued operation without excessive downtime or expenses. As older motion control servos become increasingly difficult to service or replace, our extensive catalog of direct replacements offers a reliable solution. Many of these retrofit components are available in this section, with more in continuous development to meet industry demands.
At Potomac Electric, we understand the time and cost pressures of maintaining automation equipment. When replacement isn’t an option, our expert repair services provide a high-quality, cost-effective solution with fast turnaround times—helping you minimize downtime and keep operations running smoothly.
Below, you’ll find links to our aftermarket replacement components, organized by industry-specific OEM machines and component brands, including motors and controllers.
