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 steering angle of rear wheels of a four-wheel steering vehicle is controlled so that a quick response of an electric motor mounted in the rear wheels is achieved only when it is necessary, thereby avoiding wasteful consumption of power. In addition, a yaw rate feedback system is kept stable. When unstable vibration of the electric motor is detected, a gain to the yaw rate is adjusted.

摘要： 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.

摘要： 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.
