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 ...

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 ...

If you made a motor out of a magnet, a wire coil, and some needles, you probably remember that motors and generators depend on a rotating magnetic field. Once you know how it works, the concept is ...

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 ...

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 ...
