A stator and a rotor arranged so as to face each other along an axial membrane, in which a permanent magnet for the field of the rotor is arranged on the outer periphery of the rotor yoke, and A first rotor facing portion is provided on the outer peripheral portion of the stator yoke to face the inner peripheral surface of the permanent magnet in the radial direction with a gap therebetween, and a first rotor facing portion is provided on the stator yoke so that the first rotor facing portion A second rotor facing part is provided protrudingly located on the inner peripheral side of the rotor yoke and faces the rotor yoke with a gap therebetween, and the stator is arranged such that the armature coil is wound around the second rotor facing part. A permanent magnet DC motor characterized by being installed along a yoke. 2. The permanent magnet DC motor according to claim 1, wherein the second rotor facing portion is formed in a substantially fan shape that widens toward the outer circumferential side of the stator yoke. 3. The permanent magnet DC motor according to claim 1 or 2, characterized in that the stator yoke has a slit formed between the second rotor opposing parts. . 4 Utility model registration claim 1, characterized in that the gap between the second rotor facing part and the rotor yoke is set smaller than the gap between the first rotor facing part and the permanent magnet. The permanent magnet DC motor according to any one of items 1 to 3.
