Electro-permanent magnets (EPMs) are pretty nifty concepts, and if you aren’t familiar with them, they are permanent magnets with the ability to be electrically switched on or off. Unlike an ...
Physicists Prof. Dr. Ingo Rehberg from the University of Bayreuth and Dr. Peter Blümler from Johannes Gutenberg University Mainz have developed and experimentally validated an innovative approach for ...
An electromagnetic linear machine is an energy conversion device that can convert electrical energy into linear motion. Conventional study of electromagnetic linear machines mainly focuses on the ...
The planar magnetron is a typical diode mode sputtering cathode consisting of a permanent magnet array behind it. This magnet array is organized in such a fashion to provide a magnetic field that is ...
Various working principles have been proposed for displacement measurement of single direction motions 1,2,3,4,5,6,7, as well as planar linear motions 8,9,10. However, the emergence and development of ...
Continuing headlines about superefficient electric drives might lead some observers to wonder about the future of three-phase induction motors. The truth is that induction motors aren’t going away any ...
We recently published an article on the Power Electronics with the headline, “Unique Motor Uses Only Permanent Magnets – No Electric Power Required.” We received a firestorm of criticism that this ...
James McKenzie looks at the work of University of Birmingham spin-off firm HyProMag, which has developed a technique for recycling rare-earth magnets Growth prospects Rare-earth permanent magnets are ...
