  • Patent number: 9071108
    Abstract: There is provided a movable iron core linear actuator, which includes a magnetic circuit which causes a moving element to reciprocate. The magnetic circuit includes an iron core constituting the moving element, a stator core including a facing portion which faces the iron core, a pair of permanent magnets disposed in the facing portion along a reciprocating direction and having inverted magnetic poles at their surfaces which face the iron core, and a coil wound around the stator core. Energization to coil causes the moving element to reciprocate. When the coil is energized, the spring force of magnetic spring which changed in accordance with a relative position of the moving element with respect to the stator core is superimposed on the electromagnetic driving force produced by the energization of the coil and is applied to the moving element by the magnetic flux produced by the permanent magnets.

  • Patent number: 8643230
    Abstract: A linear actuator includes a linear actuator body (2), a casing (3) for housing the linear actuator body (2), and insulating oil (L) that fills the casing (3) with a coil (44) of the linear actuator body (2) submerged therein. In such a configuration, heat generated by the coil (44) is quickly released to the oil (L) and is then conducted to the casing (3). The oil (L) fully spreads into gaps in the coil (44), of course. Therefore, heat is released very efficiently. Thus, by improving the heat-releasing characteristic, a linear actuator having a reduced size and a reduced weight is provided.
