Magnets for Dcdisc Type Electric Motors

Sintered NdFeB permanent magnetic material with neodymium (Nd), iron (Fe) and boron (B) as the basic raw material, adding a small amount of dysprosium (Dy), terbium (Tb), cobalt (Co), niobium (Nb), gallium (Ga), aluminum (A1), copper (Cu) other elements, an iron based permanent magnet materials used in powder metallurgy manufacturing process.It is the world's most powerful third generation permanent magnet.Sintered NdFeB permanent magnetic material is the third generation permanent magnet in the world.Compared with ferrite, alnico and SmCo permanent magnet and other materials, sintered NdFeB permanent magnetic material as a result of high remanence, high coercivity, record high energy product known as "magnetic king", on the other hand, because it is a kind of iron base materials, low cost, has attracted world attention.
