SEM is a worldwide supplier of brush and brushless servo motors to system integrators of machine tools, robotics, transfer lines, and similar automation applications. SEM also supplies AC and DC permanent magnet servo motors to drive manufacturers and large OEMs.

Working on SEM servo motors for over 15 years, Potomac Electric has repaired thousands of SEM brush and brushless servo motors. We are also continuously working on developing replacements for obsolete or very expensive parts. We will update this page as more replacements become available.

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 SEM servo motors may be in our Parts Inventory, so contact us with any inquiries for small lot production.
