Bargteheide – More than two thirds of the energy consumed in industrial appli-cations goes into the operation of electric drive technology. Since an electric motor’s energy consumption makes up about 98% of its total cost of ownership, investment in efficient drive technology is more than worthwhile. Adding to that, there are binding standards for plant manufacturers and operators such as the IEC 60034-30 which will make compliance with the IE2 energy efficiency class mandatory for a large number of electric motors as of June 16, 2011. More in-formation on the new efficiency classes and details about international regula-tions are available at www.nord.com\/IE2. The following article covers which energy efficiency measures manufacturers should consider with respect to drive technology. Energy saving potential does not stop at optimizing the consumption of individual motors. Prudent efficiency measures should also consider the complete drive system together with the application process. NORD DRIVESYSTEMS has many years of experience in developing efficient drive technology and customized energy saving concepts. Apart from optimizing materials and the design of its electric motors, NORD employs such technologies as high-frequency operation, automatic magnetization adjustment, energy recovery, and intermediate circuit coupling.
\nRegenerative braking
\nWhile conventional frequency inverter applications discharge the braking energy as heat, more efficient and eco-friendly drives reuse this excess energy via intermediate circuits or regenerative braking and thus reduce the power drawn from the mains supply.
\nIntelligent control during partial load operation
\nIntelligent control is another way to save energy. For asynchronous motors, frequency inverters generally maintain the magnetic flux level required for yield-ing the full torque over the whole speed range, thus causing unnecessary losses during partial load operation. NORD’s SK 200E, SK 500E, and SK 700E-type frequency inverters can save resources by automatically reducing magne-tization when the motor is operated under partial load for potential energy sav-ings of up to 30 %.
\nIE2 motors for energy saving drive solutions:
\nnew standard-compliant units offer additional benefits
\nFor its new range of IE2 motors, NORD uses more active material in the stator and higher quality sheet metal that helps reduce losses.<\/p>\n","protected":false},"excerpt":{"rendered":"
