Abstract

PURPOSE:To improve the magnetic flux efficiency of a permanent magnet, and to contrive to miniaturize the titled actuator by placing plural coils which is wound squarely to the outer periphery of a cylindrical supporting body, in the peripheral direction, and placing the permanent magnet in accordance with the coil, on the inner peripheral side or the outer peripheral side of the supporting body. CONSTITUTION:Plural coils 11 which is wound and formed squarely in the outer periphery of a cylindrical supporting body 2 for supporting a body to be driven 1 are placed in order in the peripheral direction, and the adjacent coils 11 are constituted so that the current directions become opposite. In the inner periphery of the supporting body 2, plural pieces of permanent magnets 12 forming the upper and lower pair through an air-gap are attached through a fitting body 13 so that each adjacent one becomes a different polarity, in accordance with the coil 11. A magnetic flux generated from one permanent magnet 12 being adjacent in the axial direction crosses orthogonally one side in the peripheral direction of the corresponding coil 11, passes through the corresponding yoke 15, crosses orthogonally the other side in the peripheral direction of the coil 11, goes into the other permanent magnet 12 being adjacent in the axial direction, passes through a yoke 14 of the back part and returns to the permanent magnet 12. Accordingly, a path of the magnetic flux by the permanent magnet is shortened.
