motors with premium efficiency counterparts presents businesses with a significant opportunity to reduce operating costs. A comparison between premium and standard efficiency motors from 0.25 to 10 horsepower is conducted; comparisons of full-load efficiencies are shown, and estimated payback periods are calculated. Methods for calculating the yearly kilowatt-hour consumption and yearly cost savings of premium efficiency
motors for this horsepower range are also given. The cost advantages of premium efficiency motors are summarized, and relevant examples of real world cost savings are shown.
Our politicians in Washington continue dithering over the Obama administration energy bill aimed at developing alternative, green sources of energy production. As a result, when this country will have a viable energy program in place is anyone’s guess, given the usual D.C. gridlock. And yet, Americans can take more than cold comfort in the fact that at least some government agencies—U.S. Department of Energy (DOE)—and the private sector—some major manufacturers—are doing more than their share of work in trying to
harness our existing, fossil-based energy sources in such a way that they are used to their best efficiencies.
As automation devices have grown more complex and have incorporated more plant data in their operation, there is an increased need for programming
changes to continue smooth operation or
improve performance. In environments requiring frequent changes, it is not uncommon for code to be lost or changes
overwritten, resulting in increased downtime and decreased productivity
The Royal Danish Theatre has occupied
the heart of Copenhagen for centuries
and recently upgraded to a new control system featuring Sprint Electric DC drives to extend the lives of the existing motors, keeping replacement costs down. The Swedish stage design and technology company Visual Act retained most of the original motors and mechanics while providing a much-needed facelift to the stage.
In today’s increasingly competitive global economy, industries and the companies that serve them are always looking for an edge. Price and quality being routinely accepted as a given, businesses—large and small—are always looking for a little help. For the worldwide bearing industry, that help exists in the form of the Bearing Specialists of America (BSA).
