PROBLEM TO BE SOLVED : To provide a highly efficient ring-shaped anisotropy bond magnet, particularly a small and thin anisotropy rare earth bond magnet having multiple poles.SOLUTION : A ring-shaped anisotropy rare earth bond magnet having a plurality of poles comprises a pole region corresponding to a pole portion and a non-pole region adjacent to the pole region. In the anisotropy rare earth bond magnet, one of the pole region and the non-pole region is oriented in a circumference direction and the other thereof is oriented in a radical direction, or one of the pole region and the non-pole region is oriented in the circumference direction and the other thereof is not oriented.COPYRIGHT : (C)2006, JPO&NCIPI |
