<p>A strong magnetic thrust force type actuator includes a first type of actuator, the permanent magnet of which is inserted between plate members of the primary magnetic member. When the insulated wire is activated by the primary magnetic member, a magnetic flux flows from a facing portion formed with a secondary magnetic member to a plate member, and then, to an adjacent plate member through a permanent magnet. In this adjacent plate member, another magnetic flux flows in there from another adjacent plate member through another permanent magnet. In a second type of actuator, the permanent magnet of which is inserted between the side surfaces of facing portions formed with the secondary magnetic member, a magnetic flux flows from a facing portion formed with the primary magnetic member to a facing portion of the secondary magnetic member, and then, to an adjacent facing portion through a permanent magnet, in this adjacent facing portion, another magnetic flux flows in there from another adjacent facing portion through another permanent magnet. Thus, as long as the pulse current flows in the coils wound around primary magnetic member, all facing portions of the primary magnetic member contribute to produce a magnetic thrust.</p> |
