Abstract

PURPOSE:To improve the magnetic flux efficiency of a permanent magnet, and to contrive to miniaturize the titled actuator by placing two pairs of coils for the axial direction driving and the peripheral direction turning, consisting of plural coils which is wound squarely to the outer periphery of a cylindrical supporting body, in the peripheral direction by shifting them by 1/2 pitch to each other. CONSTITUTION: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 first coil 11 and adjacent both axial direction sides of one portion of one pair each of the upper and lower second coils 10 are passes through the corresponding second yoke 15, crosses orthogonally the other side in the peripheral direction of the coil 11 and adjacent both axial direction sides of the other portion of a pair each of the coils 10, 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 one permanent magnet. When the coil 11 is conducted electrically, a body to be driven 1 moves in the axial direction through a supporting body 2, and when the coil 10 is conducted electrically, the body to be driven 1 turns in the peripheral direction through the supporting body 2. A magnetic path becomes a short path for passing through between the permanent magnets 12 of each different polarity for forming a pair in the axial direction.
