ANSI/EASA Standard AR100-2020

Oct 05, 2020

Program Overview 

EASA AR100 assures the efficiency and reliability of repaired electric motors.

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 of the 2003 study The Effect of Repair/Rewinding on Motor Efficiency, by EASA and the Association of Electrical and Mechanical Trades (AEMT).

The intent of this groundbreaking accreditation program is to evaluate service centers for evidence of compliance 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.
