High efficiency vs premium efficiency motors
WebEnergy Efficiency Ratings. The Brazilian industrial sector consumes around 40% of the country's electric energy, and 70% of such energy is consumed by electric motors. As an initiative to reduce energy consumption, in 2009 Directive No 553 came into effect, establishing minimum efficiency levels for machinery and equipment. Webextremely high efficiency and uses state-of-the-art technologies to achieve that efficiency in a robust PMAC motor suited for low cost manufacturing. The design and tested performance of this example, a 15hp (11 kW), 1800 rpm permanent magnet motor, is suitable for comparison to NEMA Premium®/IE3 efficiency IMs, and NEMA Super …
