The third Solid Motor Annual Rocket Technology Demonstrator's (SMART Demo) static test featured propulsion technologies that ...

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 ...

Northrop Grumman tested a solid rocket motor Dec. 4 as part of an internal program to advance solid rocket propulsion ...

The agreements with MP Materials Inc and privately-held Vacuumschmelze are the latest push by GM to domestically source EV materials for its Ultium platform, a goal it hopes to achieve by 2025. The ...

When you think of electric motors, you usually think of magnets. But magnets are heavy, and good magnets can pose problems when you need lots of them. A technology called SESM (separately excited ...

Is the dependence on rare earths for electric vehicle motors soon to be over? A magnet-free innovation promises to enhance motor efficiency while being more environmentally friendly. Mahle, based in ...

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, ...

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 ...

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 ...
