Variable flux permanent magnet machines represent a dynamic class of electrical machines in which the air-gap magnetic flux can be actively adjusted during operation. This flexibility permits improved ...

A magnetic cloak works by diverting external magnetic fields so that, to an external observer, the object appears to be absent or invisible. Although this idea ...

Linear motors are becoming increasingly practical for general motion. Many are used for long strokes of a few feet or more. One new design, however, where the magnets move relative to a stationary ...

ERLANGER, Ky., May 12, 2011 (GLOBE NEWSWIRE) -- MAG IAS has received two new orders, valued at more than $26 million, from customers in the energy and heavy construction equipment sectors in Europe ...

A trio of national U.S. labs have built and tested a powerful new magnet based on an advanced superconducting material. The eight-ton magnet—about as long as a semi-truck trailer—set a record for ...
