Energy-efficient electric motors
How to get the most out of energy-efficient motors: You have to do more than just look at the motor nameplate to get maximum energy savings. Are you ready for Dec. 19, 2010, the next major U.S. motor efficiency compliance deadline?

Concern for the environment may motivate private individuals and the general public, but it’s a poor reason for making business decisions. Companies buying and installing electric motors have a far better business reason for trying to save electricity—making their operations more cost-efficient. In a rare confluence of factors, reducing electricity usage by installing more energy-efficient electric motors promotes both of these goals. And, it might be a requirement as of Dec. 19, 2010, the next major U.S. motor efficiency compliance deadline.
When one talks about high-efficiency motors, it is important to note that this term really refers to traditionally architected electric motors consisting of armature and field windings. “Induction motors are available in standard-, high- and premium-efficiency models,” said David Hansen, global product manager, Kinetix Motion Control, Rockwell Automation, “whereas permanent magnet motors are not.” The reason is that the permanent-magnet electric motor architecture is inherently more efficient, since no power is used to establish the stator magnetic field. John Malinowski, senior product manager - ac motors, Baldor Electric Company, pointed out: “ac induction motors have a family of motors that comply with NEMA Premium Efficiency per NEMA MG 1, tables 12-12 and 12-13, and IEC 60034-30 [standards] for IE3 efficiency.”

Правильное использование двигателей с высокой энергоэффективностью не ограничивается одним лишь правильным прочтением данных на щитке двигателя. В декабре 2010 г. в США ввели новые директивы, обязывающие применять электродвигатели с высоким КПД, в Европе аналогичные правила действуют уже давно. Готовы ли вы к очередным более строгим директивам?
