2019年的倒带研究
The Effect of Repair/Rewinding on Premium Efficiency/IE3 Motors
发表: 2021年1月
In response to various opinions about the feasibility of maintaining motor efficiency during repair, 包括更换定子绕组, 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. 这份有价值的出版物解释了这些发现:
2019年的研究重申了2003年研究的结果.
电机可以在不降低效率的情况下进行维修.
保持电机效率的良好操作指南
发表: 2021年1月
The original 2003 rewind study good practice guide has been editorially updated, 对任何良好的实践都没有实质性的改变. 主要针对服务中心人员, 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. 它包含维修技巧, 相关运动术语, and in为mation about sources of losses in induction motors that affect efficiency.
ANSI/EASA AR100-2020: Recommended Practice 为 the Repair of Rotating Electrical Apparatus
发表: 2020年9月
ANSI/EASA AR100 “Recommended Practice 为 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.
本文档描述了记录保存的范围, 测试, analysis and general guidelines 为 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; there为e, the EASA Recommended Practice is the standard 为 repair of rotating electrical apparatus.
EASA AR200-2021: Guide For The Repair Of Dry-Type Trans为mers
发表: 2021年8月
This updated guide outlines best practices 为 the repair of dry-type trans为mers.
先前版本的 AR200 (出版于2011年)的标题是 Guide For The Repair Of Power And Distribution Trans为mers. 和之前的版本一样, it embraced a broad scope of trans为mer repair that included liquid-filled distribution or power trans为mers up to 10 MVA and 69 kV.
在准备更新的过程中, the Technical Services Committee chose to narrow the scope to the types of trans为mer repair activities usually found in EASA service centers (i.e., non-liquid-filled distribution dry-type trans为mers with high voltage windings up to 69 kV and rated less than 15,000 kVA). 毕竟, liquid-filled trans为mer repair and service is a specialty few members offer, with many standards and best practices differing from those 为 dry-type trans为mers.

三相定子绕组故障
The life of a three-phase stator winding can be shortened dramatically when the motor is exposed to unfavorable operating conditions — electrical, 机械或环境. The winding failures shown are typical of what can happen is such circumstances. You can also order copies of the brochure detailing these failures.
