    摘要: Disclosed is a linear actuator which includes a core, a coil, a magnet assembly, and a housing. The coil that is shaped to be positioned about the core for movement along a longitudinal axis of the core. The housing is supported by core flanges and positioned about the coil and the core. The magnet assembly includes magnets of the same polarity facing the coil and shaped to be positioned inside or outside of the coil, and supported by the core or by the housing, respectively. The core includes first and second portions, each having an end face, and the first and second portions are positioned along the longitudinal axis so that the end faces oppose each other and are separated by a gap. A cavity is formed in each of the end faces along the longitudinal axis.

    摘要: The permanent magnet is mounted within the coil in engagement with the magnetic frame so when the coil is energized by a pulse of DC voltage of polarity giving a coil flux aiding the magnet the plunger is actuated against the bias of the spring to move the plunger close enough to the magnet to be retained. A pluse of opposite polarity gives a coil flux opposing the magnet flux so the holding force is less than the spring force and the plunger is moved to its inactive position.

    摘要: A linear voice coil actuator is disclosed which includes field subassemblies each including a field blank, and in which at least a one of the field subassemblies includes magnets of alternating polarity positioned on the field blank to form interleaved-magnetic circuits in a direction of motion of the linear voice coil actuator. The field subassemblies are positioned with respect to one another to form a gap between the field subassembly having the magnets, and another of the field subassemblies. Also included is a coil assembly that includes coils positioned in a plane within the gap, wherein the plane is substantially parallel to the direction of motion of the linear voice coil actuator. The field blanks include flux path sections which provide a flux path perpendicular to the direction of motion for each pair of magnets of opposite polarity that are separated by the gap, and which thereby results in the height of the actuator of the present invention being largely independent of the lengths of the magnets employed.
