Abstract
A fan motor includes: a stepping motor for rotating a rotating shaft; an impeller rotated by the rotating shaft; and a connecting member for rotatably connecting the impeller relative to the rotating shaft. The connecting member absorbs an inertia force of the impeller while idly rotating the rotating shaft relative to the impeller in starting the motor and rotating the impeller to follow the rotating shaft as a revolution number of the rotating shaft increases.
