PURPOSE:To obtain a rotary force without necessity of electric power by utilizing the repelling of the magnetic forces of permanent magnets therebetween for the rotary force of a rotor. CONSTITUTION:Four ferromagnetic units 6 capable of being inserted from the outside of a case 5 inwardly and fixed to the intervals are arranged between rotary discs 1 disposed at an equal interval to be equally divided at the circumference of the case 5, and opposed in the same polarity to the permanent magnet 2 of the disc 1, and opposed to maintain the prescribed interval between the permanent magnet plate 2 and the stational permanent magnet 6. With this construction, the permanent magnets are repelled at four positions on the circumference therebetween at the side face of the disc 1, thereby rotating the disc 1. Only the rotary force can be applied in the prescribed direction by covering the stationary permanent magnet 6 with a magnetic force shielding plate 7. |
