EASA’s “Recommended Practice for the Repair of Rotating Electrical Apparatus” is designated ANSI/EASA AR100 and was first approved as an American National standard in 1998. Since then it has been revised and approved four more times, in 2001, 2006, 2010, 2015 and now in 2020.
ANSI/EASA AR100 is a must-have guide to the repair of rotating electrical machines. Its purpose is to establish recommended practices in each step of the rotating electrical apparatus rewinding and rebuilding processes.
The scope of this document describes record keeping, tests, analysis and general guidelines for the repair of induction, synchronous and direct current rotating electrical apparatus. It is not intended to take the place of the customer's or the machine manufacturer's specific instructions or specifications or specific accepted and applicable industry standards or recommended practices.
This document should be supplemented by additional requirements applicable to specialized rotating electrical apparatus including, but not limited to, listed explosion-proof, dust-ignition proof, and other listed machines for hazardous locations; and specific or additional requirements for hermetic motors, hydrogen-cooled machines, submersible motors, traction motors, or Clas 1E nuclear service motors.
ANSI recognizes only one standard on a topic; therefore, the EASA Recommended Practice is the standard for repair of rotating electrical apparatus.
