Premium efficiency
Premium efficiency, when used in reference to specific types of Electric Motors (with a rotating shaft), is a class of motor efficiency. As part of a concerted effort worldwide to reduce energy consumption, CO 2 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 electrically powered 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.
