<P>PROBLEM TO BE SOLVED: To provide a rotor using a permanent magnet, in consideration of the defects of the permanent magnet which makes it hard to put it into practical use, the defects including: 1)magnetic force is weak; 2)change of magnetic pole is not easy; and 3)a rotation is small and cannot make a single rotation. <P>SOLUTION: A rotor plate 1 is positioned in front of and at the back of a fixed frame 4 so that repulsion force is twice as large. Magnet pieces are fixed at equal angle positions around the rotor plate and are connected by a guide plate. A rotation is made possible by connecting a plurality of rotors. The rotor rotates along the shape of the guide plate by the rotation of the rotor plate and expands by a force of a spring. The shape of the guide plate is designed so that mutual magnet pieces come closest when the magnet pieces of the rotor plate pass through the magnet pieces of the fixed frame. A rotation is made possible by connecting a plurality of rotors. A position of a movable body installed on the fixed frame of the connected rotors is different and enables consecutive rotations by repulsion force before stopping by being positioned within a rotatable angle where one rotor is capable of rotating. <P>COPYRIGHT: (C)2012,JPO&INPIT |
