The leading German tech giants over at Mahle have developed an electric motor that doesn’t use permanent magnets. It has the potential of powering a wide range of vehicles, it’s highly efficient, and ...

We recently published an article on the Power Electronics with the headline, “Unique Motor Uses Only Permanent Magnets – No Electric Power Required.” We received a firestorm of criticism that this ...

While electric vehicles certainly offer a host of eco-friendly advantages, they're not without some asterisks, one being the rare earth materials (and harmful mining thereof) used to make the magnets ...

We've hinted at the impressive power output of the BMW iX M60 motor in our First Look, but its fifth-generation electric motor technology deserves its own examination. That's because it's both ...

UQM Technologies has secured US$3m from the US Department of Energy (DOE) to develop non-rare-earth magnet electric motors for use in electric and hybrid electric vehicles. “We are pleased the DOE has ...

Continuing headlines about superefficient electric drives might lead some observers to wonder about the future of three-phase induction motors. The truth is that induction motors aren’t going away any ...

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 ...
