    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.

    摘要: A linear actuator, wherein a permanent magnet is reliably prevented from being damaged. In a first linear actuator, the width of a gap between a first contact section and a second contact section in a radial direction or the width of a gap between the first contact section and the second contact section in a rotating direction is less than the width of a gap between a permanent magnet and a magnetic pole section. In a second linear actuator, a flat plate-like permanent magnet is provided in that one of a movable section and a stationary section which is provided with a coil for generating a magnetic flux for reciprocating the movable section, and that surface of the other which is opposed to the permanent magnet and functions as a magnetic pole surface is formed flat. In a third linear actuator, each of an engaging projection and a cutout is provided so as to be oriented in the direction in which the magnetic force of the permanent magnet acts on the magnetic pole section. At least a portion of the cutout is notched in the direction in which the magnetic force of the permanent magnet acts on the magnetic pole section.

    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.
