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 ...

The Ecoheart family of high-efficiency permanent-magnet motors and drives achieve 10% higher efficiency because internal power loss is reduced by 50%. The high-performance magnets and a new method for ...

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 ...

A team led by Physics professors Kai Liu and Gen Yin and graduate student Willie Beeson (G’25) has discovered a new class of strong magnets that do not rely on rare-earth or precious metals — a ...

Have you ever wondered how switchable magnets work? Not electromagnets, but those permanent magnet fixtures like the ones that hold dial indicators to machine tools, or the big, powerful chucks for ...

Mkango Resources and the University of Birmingham have commissioned a commercial plant for recycling rare earth magnets. The ...

The origins of magnetic steel can be traced back to the 18 th century when scientists began experimenting with iron alloys. In 1820, Hans Christian Oersted's accidental discovery of electromagnetism ...
