Dr Medraj believes the magnets they are developing will be significantly cheaper and have greater thermal stability than neodymium based magnets - which are the strongest rare-earth magnet
Reclaiming of rare-earth magnet
motors/generators used in (H)EVs is a major challenge because the magnets are difficult to remove from the assemblies.
The new design provides a similar level of performance as UQM Technologies' current design which use permanent magnet motors with rare-earth magnet
Using a polycrystalline model of a rare-earth magnet
, the model is divided into extremely small regions of 1 nm.
This company has introduced a new class of high-energy, elastic rare-earth magnet
material called Reance SF.
The RH mini actuators combine zero backlash harmonic drive gearing with rare-earth magnet
DC servo motors to provide both high torque and positional accuracy better than 2 arc-minutes.

The Direct System, unlike a hearing aid which simply amplifies sound, turns sound into electromagnetic waves which vibrate a tiny rare-earth magnet
implanted in the middle ear.
The Direct System consists of a tiny, rare-earth magnet
implanted in the middle ear, and a speech/sound processor.
Among the total exports, the export volume of rare-earth magnet
, exporting to 69 countries and regions, reached 21,532 tons, nearly doubling against the pervious year, and the export value was US$415 million, up 36.
material is available for enhanced product purity.
