Potomac Electric has worked with MCG (QMC) for many years. We have provided repair services for the Eastern part of the USA. After Ametek purchased MCG, many models of servomotors became obsolete and customers have asked us to make replacements.  A number of Form, Fit, and Function replacements are in the table below. You can find more under the Replacements by Industry tab. Replacements save a lot of money in machine maintenance and avoid costly retrofits.

Contact us. We may have already solved your problem!

The list of MCG 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 MCG servo motors may be in our Parts Inventory so contact us with any inquiries for small lot production.
