AC/DC Electric Motor Repair

Including SERVO - in house

Chattanooga Armature Works is an EASA Motor Shop.  We follow industry standards of the Electrical Apparatus Service Association.  EASA is a professional trade organization whose mission it is to facilitate standards, education, and best practices to members who serve as total solution providers for electrical and mechanical equipment and systems.


We provide excellent quality and quick turnaround time because we understand that you don't have time to wait.  We do everything we can to make your job easier.


Our services range from new motors to basic rehab, preventative repair, and complete motor rebuild:

Our services extend well beyond electric motor & motor control sales & repair. In order to provide the best, most complete service possible, we recognize that you need a Motor Shop that can help with the full concept of Power Transmission. So, we have a full machine shop with ability to fabricate, weld, modify, and repair. Laser Alignment and Dynamic Balancing are other capabilities that we offer.

In today's demanding market, you can't wait for a failure and a plant shut down, so, we can help you with PdMA Predictive Maintenance Testing and Vibration Analysis

In 2015, we expanded our services to include SERVO MOTOR SALES & REPAIR.

We perform this work in house by a specialized technician with decades of experience in the motor industry. CALL US AND LET US QUOTE YOU!

A fully-equipped machine shop is an essential piece of an electric motor repair  facility.  It is necessary to check tolerances on all machined fits as well as be able to fabricate new shafts, weld motor parts, repair bearing housings, and much more.  Having a machine shop allows us to turn around jobs much more quickly as we don't have to wait on a supplier.
