PROBLEM TO BE SOLVED: To reduce power consumption, by decreasing energy consumption by copper loss, such as loss of exciting coil. SOLUTION: A driving mechanism for driving a magnetic member is constituted through operation of switching a magnetic pole at a pole edge by controlling the current of magnetic flux from magnetic flux generation source 2. A magnetic drive mechanism 1 includes a first magnetic component 4 of and the second magnetic component 7, having magnetic flux generation sources 2 and 5. A first magnetic component 4 formes a magnetic circuit through the magnetic flux generation source of the first magnetic component and the magnetic induction path, and a magnetic flux control means 8 for controlling the flow of magnetic flux, which flows in a magnetic circuit on this magnetic circuit, is provided. The second magnetic component 7 is located among two or more pole edges formed in the middle of magnetic circuit. The magnetic flux control means 8 controls the flow of magnetic flux over the pole edge, by controlling the magnetic characteristics of the magnetic induction path so that balancing of the strength of the positive/negative of each magnetic pole of pole edge is changed, and the direction of magnetic flux to the second magnetic component is changed. Then, the first magnetic component and the second magnetic component are moved relatively. COPYRIGHT: (C)2007,JPO&INPIT |
