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 ...

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 ...

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 ...

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 ...

IE5+ permanent-magnet synchronous motors  deliver constant high efficiency and torque over a wide speed range, reducing ...

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

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 ...
