Washington, D.C., has spent the past five years fixating on rare earths—where they’re mined, how they’re processed, and who controls the magnet supply chain. That attention is overdue. But the ...

Since the boom of the NdFeB magnets industry, the usage and potential applications for permanent magnet machines have grown exponentially to the detriment of traditional induction systems. In special ...

Sizing conductors and protection for rotating electrical equipment is commonly required in the field and on exams. The rules ...

GM and Niron have teamed up to pry the EV motor material supply chain away from China. Did you know GM invented the domestic, affordable permanent magnet? Before this neodymium-iron-boron magnet came ...

Scientific American is part of Springer Nature, which owns or has commercial relations with thousands of scientific publications (many of them can be found at www ...

Today, most electric machines operate with radial flux (RF). Magnax offers a new concept, though—a machine that operates with axial flux (AF). Figure 1 provides a comparison of the RF and AF ...

Scientists at the Department of Energy’s Ames Laboratory have discovered rare-earth-like magnetic properties in iron under some special circumstances, which might spare the industry of using scarce ...

The latest in-line shaft generator from ABB is designed to enable ship operators to benefit from the multiple advantages of permanent magnet technology. The new generator brings flexibility and ease ...

Engineering efforts to simulate radial-flux machines concentrate on inherently 2D problems. Most of the 2D FEA software is good for "quick-and-easy" solutions demanded by shorter design schedules.
