The rotor has a rotating body that holds a permanent magnet in the circumferential direction so that the permanent magnet faces the stator, and a shaft that has the rotating body fastened thereto so as to penetrate through the center of the rotating body. Both of the bearing on the output shaft side and the bearing opposite the output shaft side journal the shaft. One of the brackets fixes the bearing on the output shaft side, and the other of the brackets fixes the bracket opposite the output shaft side. The brackets are electrically connected to each other, and a dielectric layer is formed between the shaft and the outer periphery of the rotating body.
