Abstract: The pulsewidth modulation (PWM) effect plays a critical role not only in permanent magnet (PM) loss but also in PM temperature distribution. This article proposes an analytical method to ...

Abstract: This paper proposes a nonlinear magnetics model for Permanent Magnet Synchronous Machines that accurately captures the effects of magnetic saturation in the machine iron and variations in ...

As Beijing's new licensing rules on samarium and related materials restrict exports of these heat-resistant magnets, America's ability to produce precision-guided munitions has come under pressure.

Tomahawk missiles are coveted by militaries around the world because they can hit a target 1,000 miles away. That accuracy is possible because their fins use powerful magnets made of samarium — a rare ...

When we think of Christmas, we often picture frigid temperatures and snow — even in warmer states that don’t typically see much of either. But this year, it truly is beginning to look a lot like ...
