MOTOR EFFICIENCY COMPARED AC / EC ErP "Ecodesign" Directive EU 327 / 2011 - A few questions and choices explained What does the Regulation cover? Minimum efficiency levels for commercial fans with an input power of between 125 Watts and 500 Kilowatts in the EU marketplace. Electric motors can be divided into two types: alternating current (AC) electric motors and direct current (DC) electric motors. A DC electric motor will not run when supplied with AC current, nor will an AC motor run with DC current. However if you Electrically Commutate (EC) a DC motor will operate, hence the term EC motor....
