Application

Permanent rare earth magnet materials are the largest consumer realm. At present, the mainly permanent rare earth magnet material is neodymium magnets (NdFeB), the component comprises about 30% of praseodymium-neodymium and 2% Dy-Fe. Permanent NdFeB magnet is used widely in wind power, energy-saving appliances, automotive power steering system (EPS), energy saving and environmental protection and other areas of new energy vehicles are widely used. In addition, field of consumer electronics is also applicable to hard disk voice coil motor (VCM), CD-ROM drive, micro motor and so on, as well as electro-acoustic equipment, magnetic separator, electric tools and MRI and other traditional areas. Currently, the NdFeB main contender is the ferrite magnet.

It’s expected to increase demand for permanent NdFeB magnets, because of the development of new energy vehicles. The quantity of permanent neodymium magnet for a new car’s motors is about 3 times than the conventional powered vehicles’.

Permanent NdFeB magnet is mainly used in wind power’s permanent magnet direct-drive motor. Wind power field is a relatively new applications for permanent neodymium magnet, the amount of wind power neodymium motor is relatively large, a 1.5MW direct drive permanent magnet wind generator approximately need 1 ton of NdFeB .
