    • PROBLEM TO BE SOLVED: To increase carrying mass for a linear electromagnetic type micro actuator employing a ring-shaped permanent magnet for a movable part and to stabilize continuous carrying motion. SOLUTION: In the linear electromagnetic type actuator in which a movable part 4 of the ring-shape permanent magnet is equipped with a stationary part 1 which forms a coil matrix arranging a lot of flat coils 2 in array shape, the flat coils arranged along a migration pathway of the movable part on the stationary part are selected and the movable part is driven by sequentially switching its coil's excitation according to a movement of the movable part, a longitudinal double flat coil, facing front and rear sides of the ring-shaped permanent magnet against the migration direction of the movable part out of the flat coils, is selected, excited and controlled. This stabilizes carrying motion since the carrying mass against coil conduction current is increased as well as ripple of electromagnetic force acting between an exciting coil and the movable part is deceased.
