摘要： A power generator includes an electromagnet for generating a rotating magnetic field when being excited by a three-phase alternating current applied thereto, a rotation output shaft rotatably supported on a supporting member in such a manner as to be positioned in the rotating magnetic field, and permanent magnets disposed around the rotation output shaft in such a manner that the polarity thereof is reverse to that of the rotating magnetic field. The permanent magnets are rotated together with the rotation output shaft, and magnetic bodies disposed outside the permanent magnets in such a manner as to be rotated together with the rotation output shaft. A magnetic flux of the permanent magnets passes through the magnetic bodies. Magnetic tooth portions are provided around outer peripheral portions of the magnetic bodies. Each of the magnetic tooth portions has a width being nearly equal to the width of the rotating magnetic field. When the electromagnet is excited, the magnetic flux is converged on the rotating magnetic field side and is rotated together with the rotating magnetic field, whereby the rotation output shaft receives a rotating torque.
