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 damper for automobiles capable of producing good damping effect with a simple structure while ensuring high reliability. The damper is used for reducing the vibration of an automobile body and attached to the automobile body. The damper comprises an actuator for driving an auxiliary mass, a current detector for detecting the current flowing through an armature of the actuator, means for detecting the terminal voltage applied to the actuator, a computing circuit for computing the induced voltage of the actuator from the current detected by the current detector and the terminal voltage and computing at least one of the relative speed of the actuator, the relative shift thereof, and the relative acceleration thereof, and a control circuit for driving/controlling the actuator according to at least one of the relative speed, relative shift, and relative acceleration of the actuator computed by the computing circuit.
