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.
这个市场的迅速发展具有良好的记录。2009年,两家供应商控制了该市场的大部分份额,主要集中于钕基磁体的设计。到2013年,有二十家供应商加入这个领域的竞争,包括传统的低压电机制造商以及终端设备制造商,带来了他们现有的以及新的IE4电机技术。尽管国际电工委员会(IEC)仅仅在2014年初定义了异步起动,IE4电机的异步版本,但供应商从2009年开始就已经把IE4电机作为“超高效”电机推向市场,并持续从机械工业取得积极的市场反应。
