  "textContent": "A motor (25) has a rotatably supported rotor core (34) and permanent magnets (30) disposed at equal intervals at a plurality of positions in a circumferential direction of the rotor core. The rotor core (34) has projecting poles (57) formed at equal intervals at a center between each permanent magnet (30). Furthermore, an opening angle center line of each projecting pole (57) conforms to a center line of an angle created by each opening angle center line of two adjacent permanent magnets (30). Additionally, each projecting pole is shaped asymmetrical to a line connecting a center of the projecting pole in the rotational direction of the rotor core and an axis center of the rotor core. A center in a density distribution of magnetic flux which is generated in the projecting pole is shifted in a direction opposite the rotational direction of the rotor. Therefore, the magnet torque can be sufficiently utilized, thereby a motor can be downsized.",
