Motor Repair Specifications

Not only you the motor owner, but your motor repair shop deserves to know what you expect when motors are repaired for your facility. The majority of motor repair shops in the USA are members of a technical group known as EASA (Electrical Apparatus Service Association). EASA provides a broad range of support services for motor shops, including basic motor repair guidelines (EASA AR100). EASA motor shops are expected to honor the minimum EASA requirements, but capability and compliance assessments of motor shops often prove otherwise. Industrial motor owners need their own plant specific motor repair specifications because the EASA AR100 publication does not address issues specifically related to the motors at your facility. As a minimum, a first-rate motor repair specification covers important details regarding:

1. Motor Repair Authorization
2. Motor Inspection & Assessment
3. Motor Testing Requirements
4. Motor Rewinding Requirements
5. Laminated Core Testing & Repair Requirements
6. Shaft, Motor Housing & Machined Fits Certification & Repair Requirements
7. Varnish Treating or Vacuum Pressure Impregnation (VPI) Requirements
8. Dynamic Balancing Requirements
9. Bearing & Lubrication Requirements
10. Performance Testing Requirements
11. Internal & External Coating (painting) Requirements
12. Shipping Requirements
13. Job Documentation & Recordkeeping Requirements
