形状であることを特徴とするモータ用ロータ。[Claims for Utility Model Registration] A step for driving a rotor magnet through a certain space at least on one of the magnetized end faces of the rotor magnet, using a rotor magnet magnetized with multiple poles in the axial direction. - In a motor having a rotor magnet, each of the multiple poles of the rotor magnet has approximately the same shape, and the magnetized shape of each pole is such that the distance from the rotor center axis to the outer periphery of the magnetized shape is above the center of magnetization. A rotor for a motor, characterized by having a magnetized shape that is longest at , and becomes shorter as it moves away from the center.
