Potomac Electric



Potomac Electric worked with SEM for many years. We provided repair service. Over the years products became obsolete and customers asked us to make replacements. A number of Form, Fit and Function replacements are in the table below. You can find more under Replacement by Industry tab. Replacements save a lot of money in machine maintenance and avoids costly retrofits.

Contact us. We may have already solved your problem!

The list of SEM 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 the machinery. Please drop us a note at our Contact Us page with any questions.

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