Researchers at the Tokyo University of Science (TUS) have developed a new way to perform the coercivity analysis of magnetic materials by using a combination of data science, machine learning (ML) and ...

Scientists have explored on an atomic level how changes in iron content influence the micro-structure of samarium-cobalt based permanent magnets. In the long run, they could contribute to the ...

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 ...

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 ...

Permanent magnets used for motors require high energy density, or high levels of magnetism and coercivity. Coercivity is a magnet’s ability to maintain its current level of magnetism, despite exposure ...

Additive manufacturing (AM) techniques have emerged as a transformative approach in the fabrication of permanent magnets, offering near-net-shape production and bespoke design capabilities. This ...

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 ...

The left side of the figure schematically shows how a series of two-dimensional scanning electron microscopy images of an ultrafine-grained Nd-Fe-B magnet were transformed into a three-dimensional ...

(Nanowerk News) At just a few atoms of thickness, 2D materials offer revolutionary possibilities for new technologies that are microscopically sized but have the same capabilities as existing machines ...

The majority of permanent magnet motors used in today's automobile utilize ceramic magnets in a stereotype design that is a direct descendant of the wound field motor. Designers of these motors should ...
