摘要： A bi-directional latching actuator is comprised of an output shaft with one or more rotors fixedly mounted thereon. The shaft and rotor are mounted for rotation in a magnetically conductive housing having a cylindrical coil mounted therein and is closed by conductive end caps. The end caps have stator pole pieces mounted thereon. In one embodiment, the rotor has at least two oppositely magnetized permanent magnets which are asymmetrically mounted, i.e., they are adjacent at one side and separated by a non-magnetic void on the other side. The stator pole piece has asymmetric flux conductivity and in one embodiment is axially thicker than the remaining portion of the pole piece. An abutment prevents the rotor from swinging to the neutral position (where the rotor magnets are axially aligned with the higher conductivity portion of the pole piece). Thus, the rotor is magnetically latched in one of two positions being drawn towards the neutral position. Energization of the coil with an opposite polarity current causes the rotor to rotate towards its opposite latching position whereupon it is magnetically latched in that position.

摘要： A permanent magnet brushless torque actuator is comprised of an electromagnetic core capable of generating an elongated toroidally shaped magnet flux field when energized. Outside the generally cylindrical coil is an outer housing with upper and lower end plates at each end. Mounted to the end plates and extending towards each other are stator pole pieces separated from its opposing pole piece by an air gap. A permanent magnet rotor is disposed in the air gap and mounted on a shaft which in turn is rotatably mounted in each of the end plates. The permanent magnet rotor comprises at least two permanent magnets, each covering an arcuate portion of the rotor and having opposite polarities. Energization of the coil with current in one direction magnetizes the pole pieces such that each of the two pole pieces attracts one of the magnets of the rotor and repels the other magnet of the rotor resulting in a torque generated by the output shaft. Reversal of the current flow results in a reversal of the torque and rotation of the rotor in the opposite direction. Preferred embodiments are disclosed having multiple cells, i.e. a plurality of stator rotor stator combinations and/or cells in which there are a plurality of pole pieces at each stator pole plane.

摘要： Disclosed is an improved solenoid actuator utilizing an actuator position sensor which in combination with an actuator controller, adjusts the energizing current supplied to the actuator's coil. The adjustment is based upon any difference between an actual position of the actuator and a desired position of the actuator. If there is a difference, the controller changes the energization of the actuator's coil so as to actively move the actuator to the desired position. The improvement can be utilized with existing rotary and linear proportional actuators as well as any other solenoid-type actuator.

摘要： Disclosed is a dual working airgap force motor. A centrally located stator includes two toroidally shaped electromagnets wherein the axis of the stator coincides with the axis of the toroids, each toroidal coil is separated from the other toroidal coil by an axial distance. Toroidal permanent magnets are also mounted preferably inside the toroidal electromagnet coils and also spaced apart in an axial direction. The permanent magnets generate a flux flow in opposite axial directions whereas, upon energization, the toroidal coils generate flux flow in the same axial direction at a given radial position. Two armatures are located on an output shaft, in a preferred embodiment at either end of the stator, and each armature is spaced apart from the stator by inner and outer axial airgaps. Energization of the coils with current causes a greater flux flow across the inner and outer airgaps at one end than is caused through the inner and outer airgaps at the other end tending to reduce the airgap at the end with the largest flux flow consequently causing movement of the respective armatures and the output shaft upon which they are mounted.

摘要： A rotary actuator (16) includes a rotor (48) which is disposed in a housing (34) between first and second pole pieces (42 and 44) of a stator (40). The rotor (48) is rotatable relative to the stator (48) between an unactuated position (FIG. 4) and an actuated position (FIG. 5). During rotation of the rotor (48), the axial extent of a first working air gap (66) between the rotor and a first pole piece (44) of the stator (40) remains constant. However, the axial extent of the working air gap (64) between the rotor (48) and the second pole piece (42) of the stator (40) decreases as the rotor moves from the unactuated position to the actuated position. In a preferred embodiment, the rotor lobes are made so that the net axial force of all of the rotor lobes is substantially zero thereby reducing stress on the rotor shaft support bearings.

摘要： An electronic driver circuit for reducing power consumed by a solenoid operated device. The end of the solenoid operating stroke or the existence of suitable kinetic energy in a solenoid armature is measured by reference to current flow through the solenoid coil. Current flow through the solenoid coil is subsequently terminated so as to avoid further power waste which is not contributing to any desirable increase in armature kinetic energy. In a preferred embodiment, the magnetic flux built up in the solenoid coil is applied through a suitable diode network back to the power supply, thereby reducing further the power requirements for solenoid operation.

摘要： Disclosed is a solenoid having a central and a peripheral air gap between the armature and the pole piece. The energizating coil is located in the space between the central core and the peripheral portions of the pole piece and armature. In one embodiment, an output shaft is received in an aperture in the central core of the pole piece and connected to the armature. In preferred embodiments, a longitudinally and radially extending slot is provide to produced eddy current losses. Additionally, mass is removed from non-critical portions of the armature to reduce its weight and increase its acceleration during energization of the solenoid. By utilizing stepped changes in the pole piece and armatures, peripheral portions and central core portions as well as variations in the central and peripheral gaps, the force/distance curve of the solenoid can be tailored to the specific application. In one embodiment, the armature comprises a central core which is moveable relative to the peripheral portion only in the operating direction. This permits a very small peripheral gap to generate high initial acceleration forces which are imparted to the armature central core but does not limit the central core to an inordinately short operating stroke.
