If you made a motor out of a magnet, a wire coil, and some needles, you probably remember that motors and generators depend on a rotating magnetic field. Once you know how it works, the concept is ...

As some of the world’s largest automakers ramp up production for a generation of electric vehicles, the supply of one of the most important ingredients—rare-earth elements—is surely a cause for ...

Two great minds in permanent-magnet-free motor design are fusing their know-how to create an even more capable inductive electric motor. Mahle and Valeo have teamed up to introduce what they call the ...

📼Video Summary: Electric motors can seem very mysterious! How do they use electricity to start rotating? Let's break it down step by step to understand how it works. Topics covered in this video: ...

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 ...

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 ...

Electric motors have only one moving part, but a look into the three types and how each works proves they are far from simple ...

It used to be a staple of junior high physics class to build some sort of motor with paperclips or wire. A coil creates a magnetic field that makes the rotor move. In the process of moving, brushes ...

An electric car's motors are all about magnets. Magnets in the motors turn the wheels by switching rapidly between attracting and repelling forces to spin the hub. But here's the problem: heat. Just ...

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 ...
