EASA Accreditation Program

It has been proven that electric motor efficiency can be maintained during repair and rewind by following defined good practices. EASA has developed an international accreditation program for service centers based on the sources of these good practices, namely ANSI/EASA AR100: Recommended Practice for the Repair of Rotating Electrical Apparatus and the Good Practice Guide based on the 2019 and 2003 Rewind Studies of premium efficiency, energy efficient, IE2 (formerly EF1) and IE3 motors, by EASA and the Association of Electrical and Mechanical Trades (AEMT).

To achieve EASA Accreditation, service centers undergo third-party evaluation to assure that they are using prescribed good practices to maintain motor efficiency and reliability during electrical and mechanical repairs of electric motors. The program accomplishes this by use of independent, third-party auditors.

Scope of the program
Three-phase, squirrel-cage motors that are repaired in accredited service centers. As such, the scope of the program includes mechanical repairs as well as electrical rewinding.


  • Designed to assure usage of prescribed good practices
  • Helps maintain motor efficiency and reliability during repair
  • Covers 23 categories and more than 70 criteria elements (See the Audit Checklist with Explanations for details)
  • External audits are conducted by independent, third-party auditors
