The 2019 Rewind Study
The Effect of Repair/Rewinding on Premium Efficiency/IE3 Motors
Published: January 2021
In response to various opinions about the feasibility of maintaining motor efficiency during repair, including replacement of the stator winding, the Electrical Apparatus Service Association (EASA) and the Association of Electrical and Mechanical Trades (AEMT) conducted two comprehensive rewind studies using third-party testing laboratories. This study was a follow up to a similar study conducted 2003. This valuable publication explains the findings:
The 2019 study reaffirms the results of the 2003 study.
Motors can be repaired without reducing efficiency.
Good Practice Guide To Maintain Motor Efficiency
Published: January 2021
The original 2003 rewind study good practice guide has been editorially updated, with no substantive changes to any of the good practices. Intended primarily for service center personnel, the guide which is now an independent document and not part of the complete EASA/AEMT rewind study report, outlines the good practice repair methods used to achieve the results given in both studies. It contains repair tips, relevant motor terminology, and information about sources of losses in induction motors that affect efficiency.
ANSI/EASA AR100-2020: Recommended Practice for the Repair of Rotating Electrical Apparatus
Published: September 2020
ANSI/EASA AR100 “Recommended Practice for the Repair of Rotating Electrical Apparatus”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.
ANSI recognizes only one standard on a topic; therefore, the EASA Recommended Practice is the standard for repair of rotating electrical apparatus.
