Abstract
An axial air-gap electronic motor is arranged such that a teeth surface of a stator and a magnet surface of a rotor are arranged opposedly with a predetermined gap therebetween along an axis line direction of an output shaft of the rotor. The rotor has a rotor back yoke arranged coaxially with the stator, and a rotor magnet installed to the rotor back yoke so as to face the teeth surface of the stator. The rotor magnet is provided with an anchor magnet which is integral with the rotor magnet and is arranged on a back surface side of the rotor back yoke.
