Title:
【発明の名称】動力発生装置
Document Type and Number:
Japanese Patent JP2796237
Kind Code:
B2
Abstract:
PURPOSE:To obtain a power generating apparatus having a high torque and a high energy efficiency, without any increase of its size. CONSTITUTION:A power generating apparatus has an electromagnet 11 generating a rotating magnetic field in the case of its excitation caused by the application of a three-phase AC current to it, a rotary output shaft 12 mounted in a rotatable way on a supporting member 10 so as to be placed in the rotating magnetic field, permanent magnets 14a, 14b which are so provided around the rotary output shaft 12 that the polarity of the rotating magnetic field generated by them is inverse to the one of the rotating magnetic field generated by the electromagnet 11 and which are rotated together with the output shaft 12, and magnetic substances 15a, 15b which are provided respectively on the outsides of the permanent magnets 14a, 14b and are rotated together with the rotary output shaft 12. Through the magnetic substances 15a, 15b, the magnetic fluxes of the permanent magnets 14a, 14b are passed respectively, and the magnetic substances 15a, 15b have respectively on their outer peripheral parts magnetic tooth parts 150a, 150b whose width are nearly equal to the ones of the rotating magnetic field. In case of the excitation of the electromagnet 11, the magnetic fluxes are converged on the side of the rotating magnetic field and are rotated together with the rotating magnetic field. Thereby, the rotary output shaft 12 receives a rotating torque.
