Rare earth permanent magnet materials

4, the rare earth permanent magnet materials main application

Magnet fundamental role in the space of a particular result in a constant magnetic field, the magnetic field does not need to maintain any external power supply. Signs of permanent magnet material quality of many parameters, the most important thing is the largest energy product (BH) max, the greater the energy product, per unit volume of material generated by the magnetic field, the greater the energy. NdFeB magnet material goods currently the largest energy product has reached: 50 MGOe. The rare-earth permanent magnetic materials and the high energy product, such as high coercivity of the outstanding characteristics of permanent magnet has been to bring about revolutionary changes in major applications of rare earth permanent magnetic materials in the following areas:

1. Electronic

The emergence of rare earth permanent magnet means that the electrical field will cause revolutionary changes. This is not because of rare earth permanent magnet excitation loss, fever, motor manufacturers use it many advantages. Not because of rare earth permanent magnet motor coil and the core excitation, magnet than the original size of the magnetic field very small space, no loss, fever, and to get the same output power of the components are size, weight can be reduced more than 30 percent, or the same volume weight, the output power of more than 50 percent.
