As part of a concerted effort worldwide to reduce energy consumption, CO2 emissions and the impact of industrial operations on the environment, various regulatory authorities in many countries have introduced or are planning legislation to encourage the manufacture and use of higher efficiency motors. This article looks at the development of the premium efficiency standard (IE3) and premium efficiency motors (PEMs) and associated environmental, legal and energy-related topics. ==History== The oil crisis, the Chernobyl disaster and the worldwide need for more power and consequently more power stations have raised energy conservation awareness. In 1992 the U.S. Congress, as part of the Energy Policy Act (EPAct) set minimum efficiency levels (see Table B-1) for electric motors. In 1998 the European Committee of Manufacturers of Electrical Machines and Power systems (CEMEP) issued a voluntary agreement of motor manufacturers on efficiency classification, with three efficiency classes: * Eff 1 for High Efficiency * Eff 2 for Standard Efficiency * Eff 3 for Low Efficiency 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「premium efficiency」の詳細全文を読む スポンサード リンク
