The outer ring (the stator) will hold the motor’s cryogenically cooled, high-power, superconducting electromagnets, and will also hold the levitating and positioning Halbach Arrays (consisting of ...

high-quality fields produced by complex permanent magnets for the low-emittance ring lattice design," said Shaftan. "It will be really exciting to see the hard work that led up to where we are now ...

they don't weaken as permanent magnets do, but they must be energized with currents to have any magnetic force at all. These electromagnets are generally mounted in two rings, one set within the ...

Protruding up from the center of the propeller is a small vertical ring that holds two puck-shaped neodymium permanent magnets – each one is 1 mm wide by 0.5 mm thick. Descendants of the robot ...

However, traditional magnet-free designs introduce added physical elements like the sliding rings or brushes needed ... and figuratively – relying on permanent-magnet motors.

Recycling Rare Earth Permanent Magnets by NioCorp Could Help Boost U.S. Production of Heavy Rare Earths, Which Are Currently Produced Almost Entirely in Asia The bench-scale testwork was conducted ...
