Electric Motor Repairs and Rebuilds

Stewarts Electric Motor Works specialize in the maintenance of low to medium voltage electric motors up to a 7,200 volt capacity. Additionally our cranes are certified up to 15 tons, enabling us to facilitate your more substantial motors with ease. However, here at Stewarts, regardless of size, each motor will receive uncompromised levels of commitment and dedication by our knowledgeable and experienced workforce.

May we also remind you that all our motor repairs and rebuilds adhere to energy efficient guidelines (Electrical Apparatus Service Association-EASA and the Department of Energy- DOE). For customers requiring advanced documentation and motor analysis for their critical assets, Stewart’s Quality Assurance Program offers a high value motor repair package. This includes full certification of the repair process including images and recordings of all skilled technicians and calibrated tools and machinery used during the process. However, customers with their own motor specifications will naturally receive precedent over our own programs.

Our program has also been approved for commercial, augmented nuclear motor repairs and by the Underwriter Laboratory Inc. (UL) for recertification of explosion proof motors.
