摘要： An object of the present invention is to provide a linear actuator in which reliability is improved, and performance is also easily improved. The present invention provides a linear actuator including a stator, a movable element having an iron member, and being reciprocatable with respect to the stator, a permanent magnet fixed to the stator so as to be opposed to the iron member, and a coil fixed to the stator. Because both the coil and the permanent magnet are fixed to the stator, electrical current does not have to be supplied to the movable element, and the feeder lines connected to the coil will not be broken due to the movement of the movable element. In addition, the weight of the movable element will not be increased even when the weigh of the permanent magnet is increased in order to obtain high magnetic flux density for improvement in performance. Moreover, because the movable element does not include a magnet, a magnetizing operation does not have to be applied to the movable element. The permanent magnets may be a pair in which the directions the magnetic poles thereof differ from each other, and two pairs of permanent magnets may be provided. The number of magnetic fluxes that run through the magnetic pole elements and the iron member can be increased by providing a magnetic reluctance section around the permanent magnets.

摘要： A strong magnetic thrust force type actuator includes a first type of actuator, the permanent magnets of which are inserted between plate members of the primary magnetic member. When a coil disposed upon the primary magnetic member is energized magnetic flux flows from a facing portion formed with a secondary magnetic member to one of the plate members, and then, to an adjacent plate member through one of the permanent magnets. Within this adjacent plate member, additional magnetic flux flows therein from another adjacent plate member through another permanent magnet. In a second type of actuator, the permanent magnets of which are inserted between 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 of the secondary magnetic member through means of a permanent magnet, and within this adjacent facing portion, additional magnetic flux flows from another adjacent facing portion through means of another permanent magnet. Thus, as long as the pulse current flows within the coils wound around the primary magnetic member, all facing portions of the primary magnetic member contribute to the production of the magnetic thrust.
