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 ...

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 ...

AML's permanent magnets are sized, shaped, and magnetized to optimize performance and cost of end-use products MELBOURNE, Fla., March 25, 2025 /PRNewswire/ -- Advanced Magnet Lab, Inc. ("AML" or the ...

Permanent Magnet AC motors hold the largest market share because they are more efficient, have a higher torque-to-weight ratio, and perform better in variable speed applications than other motors.

A number of readers questioned the veracity of the technology presented in this article. To address their concerns, we did a follow-up, which can be found here. Permanent magnets are an integral part ...

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 ...

The high-energy-product neodymium rare-earth permanent magnet (RE-PM) was discovered in the early 1980s. Later, dysprosium doping emerged to provide reasonable RE-PM magnetization life by sacrificing ...

Disc motors are permanent-magnet stepping motors that exhibit performance comparable to that of hybrid motors. Rotors in disc motors are thin (typically less than 1-mm) discs, unlike the cylindrical ...
