The flexibility of magnetization of isotropic thick-film magnets enabled us to enhance the torque of a millimeter-size motor comprising a multipolar magnetized rotor compared to the torque of a miniaturized motor using an anisotropic Nd-Fe-B sintered

The prediction of flux loss due to exposure at an elevated temperature is very important in applications of Nd-Fe-B magnets because of the low Curie temperature of the Nd2 Fe14 B. Previously, we proposed the prediction method of the initial flux loss

In the preparation of a miniaturized rotor, a composite bonded magnet was fabricated by taking advantage of self-recoverability. A preformed magnet was synthesized by using incomplete three-dimensional network molecular structure which was formed und

When a radially anisotropic rare earth bonded magnet for a rotor with a high (BH) max value is magnetized multi-polarly, its flux distributes rectangularly and increases a cogging torque. In order to overcome this difficulty, we newly developed highl
