摘要
An anisotropic bonded magnet (MAGFINE25), is about to be applied to dc motors for automobile use such as power seat motors and window motors. These dc motors have achieved a 50% reduction in weight and in volume, with the heat resistance of 120 degrees C. However, the heat resistance of 150 degrees C is required for motors near the engine, such as fan motors and wiper motors. We improved the heat resistance of the bonded magnet by the addition of Dy element to magnet powder, and succeeded in developing a bonded magnet with the heat resistance of 150 degrees C.
