Rare Earth Magnets

Rare-earth magnets are strong permanent magnets made from alloys of rare-earth elements Developed in the 1970s and 1980s rare-earth magnets are the strongest type of permanent magnets made producing significantly stronger magnetic fields than other types such as ferrite or alnico magnets The magnetic field typically produced by rare-earth magnets can exceed 1 4 teslas whereas ferrite or Get price

Electric vehicle traction motors without rare earth

Rare earth magnets (along with other types of permanent magnet) are always 'on' whether the electrical machine where they are used is operational or not This means that when a rare earth magnet (or other magnet based motor) is rotating even with no electrical current applied magnetic flux will still be present within the machine Get price
