摘要： A magnet assembly includes a back iron and an array of magnets. The back iron is in the form of a plate having opposed surfaces. The magnets are arranged along one of the surfaces, with the other surface being dimensioned and configured according to the magnetic field distribution associated with the magnets. The back iron geometry provides for reduced mass, reduced leakage flux, and high flux densities to improve performance of a linear motor that employs such a magnet assembly.

摘要： A magnet assembly includes a back iron and an array of magnets. The back iron is in the form of a plate having opposed surfaces. The magnets are arranged along one of the surfaces, with the other surface being dimensioned and configured according to the magnetic field distribution associated with the magnets. The back iron geometry provides for reduced mass, reduced leakage flux, and high flux densities to improve performance of a linear motor that employs such a magnet assembly. Additionally, the back iron can be a magnetically conductive annular ring, such as is employed in a rotary motor. Moreover, the magnets can be arranged in a manner that generates a Halbach array to increase force output in a desired direction while canceling stray magnetic fields in other directions. Similar reduced-mass designs can be employed in conjunction with a back iron of a fixed cross-section and magnets of variable thicknesses, variable lengths, and/or variable widths. In a case where the arrangement is employed in a platen and forcer system, plates on both the platen and forcer may be scalloped to reduce mass.

摘要： Aspects relate to mitigation of a magnetic field produced by one or more units to be shipped such that a magnitude of magnetic field measured is maintained at or below a threshold level. A counter-flux is applied through the use of one or more magnets, magnet arrays, or a geometrical arrangement of magnet arrays. The strength of the counter-flux is varied by altering size, shape, number, polarity and/or location of the one or more magnets or magnet arrays. The one or more magnets or magnet arrays can be constructed as standard assemblies and/or customized magnet assemblies. Additionally, magnet tiles or configurations can provide a return path for stray field leakage and mitigation. Additionally or alternatively, the placement and orientation of the magnets or magnet arrays allows the flux of one or more units to be mitigated, thus, allowing more than one unit to be shipped at the same time.

摘要： A linear actuator, method of manufacturing and method of using the linear actuator are provided. The invention includes a linear actuator having a plurality of annular magnets surrounded by a bobbin assembly having a coil system. The plurality of annular magnets can be arranged with alternating polarity. The bobbin assembly can be movable along a longitudinal axis extending through the plurality of annular magnets and can further comprise a coil system having coils arranged to, when energized, interact with at least one of the plurality of annular magnets to move the bobbin in a linear mode. Thus, by selectively energizing one or more of the coils, a motive force can be generated on the bobbin assembly by interacting with fields generated by the plurality of annular magnets.
