As most of the world continues to transition towards higher efficiency IE2, IE3, and NEMA high-efficiency low-voltage motors, IE4 motors, which are sold as "ultra efficient" motors in the industrial machinery market, quickly occupy their place in the high-efficiency motor market.

According to market research, since 2009, the IE4 motor market has continuously recorded double-digit growth rates, with its market share almost doubling. In 2013, the market capacity reached $114.7 million, with nearly 259000 units shipped. Although this market is still relatively small compared to the global integer power low-voltage industrial motor market, as a niche market for high-efficiency motors, it is expected that IE4's market share will grow strongly to $297 million by 2018. We believe that the growth of this low-voltage motor segment market has been ignited by regional legislation for single machine low-voltage motors.

It is worth noting that government legislation does not stipulate that IE4 ultra high efficiency motors must start selling on a specific date, as IE2, IE3, and NEMA high-efficiency motors do. The decision to purchase these motors in the industrial machinery market is purely based on factors such as high efficiency and faster investment returns.

The rapid development of this market has a good record. In 2009, two suppliers controlled the majority of the market share, mainly focusing on the design of neodymium based magnets. By 2013, twenty suppliers had joined the competition in this field, including traditional low-voltage motor manufacturers and terminal equipment manufacturers, bringing their existing and new IE4 motor technologies. Although the International Electrotechnical Commission (IEC) only defined asynchronous starting and the asynchronous version of IE4 motors in early 2014, suppliers have been promoting IE4 motors as "ultra efficient" motors in the market since 2009 and have continued to receive positive market response from the mechanical industry. We, Wanda Motor Group, have also joined this efficient, environmentally friendly and energy-saving initiative, making our due contribution to the sustainable development of humanity.
