Effect of Post-Sintering Annealing Treatment on Magnetic Properties of Some Nd Fe b Based Magnets

Effects of post-sintering annealing treatment between 300 and 1000ºC for up to 8 hrs time periods followed by either furnace cooling (FC) or air-cooling (AC) on the hard magnetic properties of some Nd-Fe-B based sintered magnets was investigated. It was shown that the intrinsic coercivity (Hci), second quadrant demagnetization loop shape and thus the energy density (BH)max varied considerably a...

Magnetic Field Analysis of Permanent Magnet Motor With Magnetoanisotropic Materials Nd–Fe–B

In this paper, we propose the method to analyze the magnetization distribution in magnetoanisotropic materials by using the finite-element method considering the improved variable magnetization and Stoner–Wohlfarth model. By using this method, furthermore, the effect of the eddy currents induced in permanent magnets was analyzed. From the analyzed result, it is clarified how the magnetization d...
