Customer Testimonials

“Potomac Electric has saved us tens of thousands of dollars every year.” – Charlie Gallant, Parts Manager, GE Aircraft Engines

"Potomac Services provides repairs and replacements for our 3000+ CNC, CMM, and other types of machines.

Potomac supports axis motors, spindles, drives, and pumps. Their quality is given, but what saves us a lot of money is the fast turnaround time. We have a lot of older machines, and Potomac is especially valuable at finding a way to get them going. They often manufacture new components, and if that’s not possible, they design form, fit, and function replacements. Potomac has been an instrumental partner in supporting us for over 15 years."

“We are impressed with their response, commitment to quality, and attention to detail, which are critical in our choice of a repair vendor.” – Randy Paper, V.P. of Quality, ArmaLite.

“When the servomotor failed on our CMM machine, we were stymied. G & L did not have the part in stock. We had to wait 3 weeks. We called around the country looking for a refurbished motor-nothing in stock. Potomac Services solved my problem by making a direct replacement in 3 days! We were running again. Potomac is our first choice to call with motor control problems.”


Newport Tool and Die Company in Rhode Island had a critical Macho CNC machine down and needed a solution fast. A power surge had caused a large servomotor to fail. Mark Nardelli, V.P. of Manufacturing at Newport Tool and Die, called Potomac Repair Services for help.

As Mark states, "The DC motor was originally manufactured by Indramat, a German company, a long time ago. We needed to minimize our downtime, so the 12 week lead time from Germany was unacceptable. Plus the cost of a new motor was close to $10,000. Potomac created a new, complex motor with brake assembly for half the price in a short period of time."

Continues Mark, "We are very pleased with what Potomac was able to do for us. They understand the urgency and financial constraints small businesses are under today. We highly recommend Potomac to every CNC machine shop."
