    摘要： A constant force generator includes a case of a tube-shaped ferromagnetic material and extending in an axial direction, a tube-shaped stator disposed in the case, and a rod-shaped shaft disposed in the tube-shaped stator via a gap. The tube-shaped stator includes N main permanent magnets magnetized in a radial direction and disposed adjacently at regular angular intervals of (360/N) degrees, and an even number of secondary permanent magnets magnetized in a circumferential direction and sandwiching each of the N main permanent magnets on both sides in the circumferential direction. The secondary permanent magnets sandwich the both sides of each main permanent magnet so that magnetic poles of the secondary permanent magnets, facing the both sides of the sandwiched main permanent magnet, have a polarity the same as an inside magnetic pole of the sandwiched main permanent magnet. The rod-shaped shaft at least includes a shaft portion of a magnetic material.

    摘要： A moving magnet motor system including a cylinder having a cylindrical axis and a rider disposed within the cylinder, wherein the rider moves longitudinally along the cylindrical axis within the cylinder. The moving magnet motor system further including a coil configured to generate an electromagnetic field, a magnet ring support structure affixed to the rider and a magnetic ring affixed to the magnet ring support structure and comprising a plurality of magnets configured to interact with the magnetic field generated by the coil to impart linear force to the rider. The moving magnet motor system further includes one or more ferromagnetic rods extending parallel to the cylindrical axis wherein the ferromagnetic rod(s) are configured to minimize or offset a bearing side load.

    摘要： A rotatable linear actuator comprises an actuator body; a drive shaft arranged within the actuator body, the drive shaft having a longitudinal axis and configured to be linearly actuated along and rotatable around the longitudinal axis within the actuator body, wherein the drive shaft is configured to be coupled at a first end thereof to a linearly actuated component that is configured to receive linear and rotational movement; one or more permanent magnets coupled to the drive shaft and magnetized in a radial direction about the longitudinal axis; and one or more electric coils disposed within the actuator body around the one or more permanent magnets and configured to receive an electric current that interacts with a magnetic field of the one or more permanent magnets to generate an axial force to linearly actuate the drive shaft. Accordingly, the drive shaft is rotatable while being linearly actuated.

    摘要： Various embodiments described herein provide a discrete focusing lens assembly. Some embodiments are designed to enable repositioning of one or more components, such as a lens barrel assembly, to adjust the focus of the discrete focusing lens assembly. Some example discrete focusing lens assemblies include a module base housing a lens barrel assembly having a pair of positioning magnets, a pair of positioning coil assemblies associated with the positioning magnets, and at least one module alignment pin positioning and/or aligning some or all of the components. The positioning coil assemblies together with the positioning magnets are configured to exert various magnetic fields to reposition the lens barrel assembly. Further embodiments are provided for imaging apparatus including at least one discrete focusing lens assembly described herein. Further, embodiments are provided for processes for assembling a discrete focusing lens assembly described herein.
