PROBLEM TO BE SOLVED: To obtain a magnet motor which eliminates a need of a brush and which reduces the generation of heat, a noise or the like, by a method wherein permanent magnets are buried at specific equal intervals in a rotating disk attached at right angles to a fixed electromagnet, and repulsion and attraction between the electromagnet and the permanent magnets are utilized. SOLUTION: A rotating drum is composed of a shaft 5 which is shaft-supported by inside frame plates 2, 2 and outside frame plates 3, 3 so as to be freely rotatable. In addition, the rotating drum is composed of a pair of disks 6, 6 which come into contact with both ends of the shaft, which are fixed to the shaft 5 and which are turned together with the shaft 5. N-poles 7 and S-poles 7 of four powerful permanent magnets at 4000 gauss or higher are buried alternately at equal angular intervals of 90 deg. on respective opposite faces of the disks 6, 6. The N-poles 7 and the S-poles 7 on the face of the disk on one side are arranged and installed in such a way that their polarities are opposite to those on the face of the disk on the other side. In addition, three pieces each of electromagnets 9 comprising respective cores 8 are fixed to the inside frame plates 2, 2 in such a way that the cores 8 are extended in parallel with the shaft 5 of the drum. At this time, the cores 8 of the electromagnets 9 are arranged at equal angular intervals of 120 deg. on the concentric circle in the same manner as the respective poles of the permanent magnets. |
