Abstract
An electric motor includes a stator that has a stator winding wound on a stator iron core; a rotor having a rotating body with a rotating shaft in the center; a bearing for journaling the rotating shaft; and two conductive brackets for fixing the bearing. The rotating body holds a magnet such that the magnet faces the stator, and is fastened to the rotating shaft penetrating through the center of the rotating body. In the rotating body, a dielectric layer is formed between the rotating shaft and the outer circumference of the rotating body. The dielectric layer has a polygonal shape with the rotating shaft in the center. An electric device includes the thus configured electric motor.
