Japanese engineers built a magnet-free electric motor with a plastic rotor, opening a surprising path for future machines.

Abstract: This article proposes torque ripple reduction methods that inject a harmonic rotating magnetic field (RMF) in the overmodulation (OVM) region of permanent magnet synchronous motors (PMSMs).

Coffee shops are usually built for comfort. A place like this has bigger plans. You might walk in expecting a latte, a pastry, and maybe a cute corner table. Then the room starts competing for your ...

Quantum physics has a long history of producing results that seem impossible until someone finds a way to watch them happen ...

Embryos have been formed from sperm that have been made magnetic to allow remote guidance towards an egg. The technique may allow IVF to be performed inside the body so it involves fewer invasive ...

CNET’s expert staff reviews and rates dozens of new products and services each month, building on more than a quarter century of expertise. There's a moment every home pizza maker knows: the raw pie ...

Abstract: The counter-rotating axial-flux hybrid-excitation permanent magnet (PM) machine is a novel power device specifically designed for counter-rotating propeller (CRP) systems. Cogging torque (CT ...
