From June 16, 2011, in accordance with EU Directive 2005/32/EC, only high-efficiency 2 to 6-pole three-phase asynchronous motors will be permitted on the European market.
They must at least comply with efficiency class IE2 (IE=International Efficiency) which corresponds to the currently highest European efficiency class EFF1. The efficiency of high-efficiency motors can be up to seven percent higher than that of standard motors, which means that less current is drawn for the same output. Drive systems consume more than two-thirds of industrial energy, so this will reduce carbon-dioxide emissions.
At the same time the operating costs are reduced for the user, such that the additional costs for the higher efficiency are paid back in a short time. The operator can therefore save around 100 Euros in energy costs by implementing a 4-pole 2.2 kW motor of efficiency class IE2 instead of an IE1 motor. In continuous duty, at a rate of eight cents per kilowatt-hour, the additional costs are paid back in a year. Replacement is easy due to the identical housing dimensions of IE1 and IE2 motors.
The Siemens Drive Technologies Division supplies all the motor series that are affected by the new legislation and has short delivery times for standard catalog motors. The user is also supported with documentation, such as data sheets, and online tools such as the DT Configurator or the Sinasave energy-saving tool.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
