摘要: In a motor, an sensor magnet is attached to a shaft and three hole sensors for detecting the position of the sensor magnet are mounted on a circuit board. By using neodymium-iron-boron base rare earth magnet having radial anisotropy as a sensor magnet, the detection accuracy for the position of a field magnet via the sensor magnet by the hole sensor can be improved.
