Magnets, typically using rare earth metals like neodymium, are found at the heart of most electric vehicle motors. It's nice to have a permanent source of powerful rare earth magnetism in your rotor, ...

The electric vehicle revolution has created market forces to drive all sorts of innovations. Battery technology has ...

Did you know GM invented the domestic, affordable permanent magnet? Before this neodymium-iron-boron magnet came along in 1984, electric motors, generators, audio speakers, hard-disk drives, and the ...

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 ...

Nearly 40 years ago, General Motors invented the rare-earth magnet and thus laid the foundation for modern electric motors. But now the automaker is moving on to a different technology. GM recently ...

The switch to a neodymium-intensive permanent magnet motor in a volume model like the Model 3 has some worried about long-term supply issues. Kyle Hyatt (he/him/his) hails originally from the Pacific ...

It's not surprising that the powertrains of electric cars differ quite a bit from traditional internal-combustion engines. Although they have fewer moving parts, the rare-earth magnets that help power ...

The IronHorse permanent-magnet dc 56C-frame motors feature totally enclosed nonvented (TENV) and totally enclosed fan-cooled (TEFC) models. Constructed of a rolled-steel frame with cast-aluminum end ...

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 ...

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 ...

There is a constant need and desire throughout the HVAC industry to spur innovation and create new products and ideas that can redefine the marketplace. In the realm of motors, the permanent magnet ...
