EMA Celebrates 29 Years In Business

Founded By A Service Engineer

EMA began in 1990 under humble circumstances. EMA founder Eddie Mayfield provided repair services on electronic motor drives from his home in Lilburn, GA for a small group of clients building trust and a reputation for quality and honesty. 

While the company has grown into a mature, mid-sized business with an array of products, services and clients of all sizes, the spirit of the company has retained the small-feeling personal touch and quality of service from those early days.  

Unmatched Service And Satisfaction

EMA provides medium voltage products and services to customers ranging from the small and local to the large and multi-national. If you google “medium voltage VFD” for instance, you’ll find that EMA is very active and noted in this field. On any given day, you’ll find EMA personnel on offshore oil platforms, cement plants, pipelines, water and wastewater facilities, and tunnel boring machines.

In 2010, EMA made a company-wide decision to shift our primary focus to medium voltage VFD service and sales. Since then, EMA has accumulated one of the largest stocks of refurbished and new medium voltage VFDs in the country. EMA has engineered load test stands to repair and test medium voltage cells from the Siemens/Robicon Perfect Harmony Series, Toshiba T300MVi, TMEIC Dura-Bilt5i, and Eaton SC9000 MV VFD. We take extreme pride in our expertise in medium voltage drives of all brands.

During these almost three decades of doing business, EMA has earned a strong reputation in the industry from peers, partner companies, and customers. In fact, EMA boasts one of the highest satisfaction rates in the industry with over 98% of all customers reporting that they are “highly satisfied” with their experience with EMA. EMA is especially known for being both able and willing to tackle tough repair and integration projects that prevent customers from having to spend many times more money on new parts and systems.

A Real Commitment To Values

At the root of EMA’s business is the commitment to a core set of values that every employee must sign when hired and which govern every aspect of how the company does business. These values not only reflect the founder’s Christian faith but allow EMA’s employees to be proud of working for a principled company. These values, along with a team of experienced and well-trained technicians and engineers, are what makes EMA a leader in the industry and a reliable partner for many businesses and business owners. It’s also what makes the team at EMA excited to continue this quality of work and service as we enter the third decade and beyond. Our aim is to prove on a daily basis that No One, ANYWHERE Is Better At Drives Than We Are!

All Persons Employed Are Expected To Embrace The Following Values:

  • All persons are worthy of respect and courtesy. This includes employees, vendors and customers.
  • All people and businesses are to be treated fairly.
  • We will be truthful.
  • We will keep our word.
  • Profanity and profane behavior are not allowed.
  • We strive to deliver our services and products on-time.
  • We strive to do quality work.
