High performance FeNdB Materials and annular geometries

Sintered Neodymium Iron Boron compounds have been formed to produce flux generating components of permanent magnet devices yielding a reduction in weight and size. The use of high energy density materials, as well as their highly thermally stable counterparts, has revolutionized the design and production of many diverse devices. Through continued development efforts, these high energy density materials have been formed into new geometries with interesting performance characteristics. The materials themselves have undergone ongoing research producing materials with remnant magnetization values in excess of 15.0 kG and intrinsic coercivities exceeding 35 kOe. The development of annular geometries in combination with the improvements in magnetic and geometrical property sets have further expanded the application of these materials.
