We’ve seen plenty of motor projects, but [Jeremy]’s DIY Tubular Linear Motor is a really neat variety of stepper motor in a format we certainly don’t see every day. It started as a design experiment ...

The global price of energy is at an all-time high, with few signs of relief in sight, making consumers and businesses alike interested in energy conservation. Currently, the most common motor type in ...

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 ...

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 ...

Disc motors are permanent-magnet stepping motors that exhibit performance comparable to that of hybrid motors. Rotors in disc motors are thin (typically less than 1-mm) discs, unlike the cylindrical ...

Recent patent disclosures indicate that BYD has strengthened its work on variable-flux permanent-magnet synchronous ...

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 ...

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 ...
