Why is EASA Critical in Electric Motor Repair?


There is so much more to the electric motor repair industry than just repairing motors. Some repair professionals go above and beyond the status quo by associating with EASA and seeking accreditation to affirm their commitment to reliability, efficiency, and performance.

What is EASA?

You may have run across the acronym EASA when looking for electric motor dealers or repair services. EASA stands for Electrical Apparatus Service Association. EASA is a formal association that motor repair shops can utilize to remain actively involved in their industry.

EASA is an international trade organization and a recognized leader in sales, repair, and service of electro-mechanical systems (which includes electric motors, generators, pumps, and powertrains). According to EASA, they "[provide] an ongoing flow of industry information and education that helps members worldwide serve as total solution providers for electrical and mechanical equipment and system."

How is EASA Organized?

EASA currently has 32 chapters that include 10 regions comprised of almost 70 countries. During the year, chapters offer workshops, training, and meetings that directly relate to the electric motor repair industry. Topics include motor root cause failure analysis, DC motor repair tips, pump repair, and high voltage winding best practices, just to name a few.

EASA Accreditation

One of the biggest contributions that EASA has made to the electric motor repair industry is their accreditation program for electric motor repair service centers. This innovative program is based on industry best practices that have been proven in the field. The two major sources used for motor repair best practices are ...

  • ANSI/EASA AR100: Recommended Practice for the Repair of Rotating Electrical Apparatus
  • Good Practice Guide of the 2003 study The Effect of Repair/Rewinding on Motor Efficiency (authored by EASA and AEMT)

If a shop is EASA accredited, that means that it follows the standards developed by EASA engineers and other associations. Those standards, including the two sources listed above, are based both on years of experience in working on electric motors and state-of-the-art advances in electric motor troubleshooting and repair. And the overarching goal of these standards is fairly simple: maintain both motor efficiency and reliability during the electrical and mechanical repair of motors.

Accreditation Process

To become EASA accredited, an electric motor repair shop must prove to a group of independent, third-party auditors that they are in compliance with the EASA standards we talked about above. The topics that a repair shop are audited for cover 23 different categories and over 70 criteria elements. This process is very difficult -- in fact, there are only 138 accredited shops worldwide out of more than 1,900 EASA member shops.

Once an electric motor service and repair shop is accredited, it has to work hard to remain accredited. This involves proving they have not become careless with complying to repair standards, becoming negligent when it comes to documentation and testing, or falling back into using outdated methods of repair. The renewal process includes annual audits as well as more visits from a third party auditor every third year


HECO has been an EASA accredited repair shop since 2016, completing a self-audit in 2017 and 2018 with their second third-party audit taking place in 2019. Here at HECO, we're also proud to say that Justin Hatfield (the president of HECO) is on three EASA committees (Marketing and Industry Awareness Committee, Emerging Technologies Committee, Membership Committee) and serves as the President of the Western Michigan chapter.


There are a lot of people out there that repair motors, and your local shop isn't the only repair expert out there and you need to remain aware of how it compares to others. One of the key measures of a repair shop's ability and its commitment to quality is whether it is EASA accredited. If you want your motor restored to original factory condition in terms of quality and performance, then seek out an EASA repair shop.
