Potomac Electric has supported Baldor servomotor and drive electronics for 20 years. Over the years products have became obsolete and customers have asked us to make replacements. Most are custom made. 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!
