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 study, led by Xianguo Gui，takes into account multiple nonlinear factors in the process of motor performance calculation. The new analytical model incorporates both main and leakage magnetic flux ...

We can’t think of a single person who doesn’t enjoy playing with a handful of rare earth magnets now and again. We know that [Dave Johnson] certainly does. As a gift to his father in law, he ...

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 ...

What do MRI machines and wind turbines have in common? They both can use superconducting magnets. It’s a discovery that GE made after decades of using the electromagnets (made out of coils of ...

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