Composite bonded magnets with controlled anisotropy directions prepared by viscous deformation technique
Abstract
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 highly dense Sm 2Fe 17N 3 and Nd 2Fe 14B-based composite bonded magnets with continuously controlled anisotropy directions by using a viscous deformation technique.
