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 ...

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 ...

IE5+ permanent magnet synchronous motors (PMSM) from NORD Drivesystems deliver the highest energy efficiency available in 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 ...

There seems to be some confusion within the industry about the terms “permanent magnet synchronous motors” (PMSMs) and “brushless DC (BLDC) motors”. I’ve talked with several different application ...

The energy-efficiency regulatory update scheduled for 2023 will affect builders of HVAC equipment, industrial fans, cooling towers and pumps, including those used in irrigation systems. The new ...

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 ...

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 ...

Tesla made a significant change to its electric motor strategy with the introduction of the Model 3, switching from an AC induction motor to a permanent magnet motor. Now, Tesla’s principal motor ...

Towards the end of July I read a post about how efficient AC induction motors are and that how using them and reducing their speed will help us all to reduce the green-house effect, save money and the ...

MUNICH, Germany—ZF unveiled an electric motor that does not require magnets or rare earth materials, reducing reliance on mining in countries such as China and cutting manufacturing's carbon footprint ...
