Abstract :
The paper describes a simplified vector hysteresis model developed for pulse magnetization of anisotropic permanent magnets. The model is tested on the magnetization of sintered and hot deformed anisotropic rings. The magnetization problem is solved by semianalytical and finite-element methods. The distribution of the magnetization vector is then imported in a static model to calculate a magnetic field around the ring. The predicted field is compared to the measured field in the open and closed magnetic circuits.
