The 2019 Rewind Study

2019 EASA/AEMT Rewind Study coverThe 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

Good Practice Guide - 2019 Rewind Study - coverPublished: 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

ANSI/EASA AR100-2020 coverPublished: 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.

EASA AR200-2021: Guide For The Repair Of Dry-Type Transformers

EASA AR200: Guide for the Repair of Power and Distribution Transformers cover

Published: August 2021

This updated guide outlines best practices for the repair of dry-type transformers.

The previous version of AR200 (published in 2011) was titled Guide For The Repair Of Power And Distribution Transformers. Like preceding versions, it embraced a broad scope of transformer repair that included liquid-filled distribution or power transformers up to 10 MVA and 69 kV.

In preparing this update, the Technical Services Committee chose to narrow the scope to the types of transformer repair activities usually found in EASA service centers (i.e., non-liquid-filled distribution dry-type transformers with high voltage windings up to 69 kV and rated less than 15,000 kVA). After all, liquid-filled transformer repair and service is a specialty few members offer, with many standards and best practices differing from those for dry-type transformers.

Failures in Three-Phase Stator Windings

The life of a three-phase stator winding can be shortened dramatically when the motor is exposed to unfavorable operating conditions — electrical, mechanical or environmental. The winding failures shown are typical of what can happen is such circumstances. You can also order copies of the brochure detailing these failures.
