While the majority of the world continues to transition to higher efficiency IE2, IE3 and NEMA Premium low-voltage (LV) motors, IE4 motors marketed to the industrial machinery market as “Super Premium Efficiency” motors have rapidly carved out a space in the high efficiency motor market.

Since 2009, this market has posted consecutive, double-digit growth rates and almost quadrupled in value in 2013 to reach $114.7 million with nearly 259,000 units shipped. Although a relatively small market compared to the entire global integral horsepower industrial LV motor market, this niche market for high efficiency motors is predicted to grow robustly to $297.3 million by 2018. We believe that growth in this LV motor market segment has been ignited by regional legislation for stand-alone LV motors.

It’s notable that no government legislation exists that mandates IE4 Super Premium Efficiency motors be sold at a certain date, like its AC induction IE2, IE3 and NEMA Premium counterparts, making the purchase of these motors by the industrial machinery market a decision based purely on the high efficiencies and the quicker return on investment.

The rapid evolution of this market is well-documented. In 2009, two suppliers controlled the majority of the market, with both focusing on a neodymium-based magnet design. By 2013, twenty suppliers including traditional LV motor manufacturers as well as end-equipment manufacturers have thrown their respective hats into the ring, bringing with them new and established IE4 motor technologies. Even though the International Electrochemical Commission (IEC) has only defined the line-start, asynchronous version of IE4 motors in early 2014, suppliers have capitalized on marketing their IE4 motors as “Super Premium Efficiency” starting in 2009 and have continued to experience a positive reaction from the industrial machinery market.
