The motor is basically a modified solenoid. There are sixteen neodymium magnets inside the shaft. The set of four coils is driven by an ATtiny44. Just like a stepper motor, energizing the coils in ...

And that’s not to mention the motors in electric vehicles and ... and it may soon be possible to build permanent magnets as strong as neodymium magnets, but without any rare earth metals.

The multiple US neodymium-magnet projects are noteworthy ... and scale as the production of motors and other magnet-dependent industries” returns to the United States, he argues.

The development of neodymium–iron–boron permanent magnets has allowed the miniaturization of motors and hard disk drives, drastically reducing the size of electronics that benefitted from ...

The collaboration could fast-track the formation of one of the world's first commercial permanent REE magnet supply chains ...
