and a rotor disposed on the outside of the cylindrical stator to face each other with a gap therebetween. The cylindrical permanent magnet is integrally formed with two small protrusions that protrude in the radial direction at symmetrical positions with respect to the outer axis, reducing the number of parts and also reducing the number of small protrusions when the cylindrical permanent magnet is magnetized. An external rotating ten-shaped electric motor characterized in that the protrusions are magnetized at the same time. （２）上記小突起を上記円筒形永久磁石の磁束最大の位
