A linear motor system includes a coil assembly, a movable magnet assembly, and a bearing assembly coupled to facilitate movement of one of the magnet assembly and the coil assembly with respect to the other. The bearing assembly includes a single bearing rail, wherein the single bearing rail is a separate component from the coil assembly and the magnet assembly and is mounted to the magnet assembly on a major face thereof opposite the major face thereof adjacent to which the coil assembly is disposed. The single bearing rail is narrower than the coil assembly and the magnet assembly. The single bearing rail includes a profiled rail configured to hold the magnet assembly on the coil assembly while allowing the magnet assembly to move along the coil assembly.

Linear motor system

A linear motor system includes a coil assembly and a magnet assembly disposed adjacent to the coil assembly. The coil assembly includes a plurality of coil windings and a sealing material to seal and to prevent moisture and/or chemical ingress into the coil windings. The magnet assembly includes a plurality of magnets, a magnet housing disposed to house, cover and seal the plurality of magnets within the magnet housing, a plate to cover the plurality of magnets, a sealing element disposed between the plate and the magnet housing to seal the magnet assembly, and a groove formed to receive the sealing element between the plate and the magnet housing.

A sealed linear motor system is provided. The sealed linear motor system includes a sealed coil assembly having a plurality of coil windings within a base plate and comprising covers disposed about the base plate and coil windings to prevent moisture and/or chemical ingress into the base plate and the coil windings. The sealed linear motor system also includes a sealed magnet assembly disposed adjacent to the coil assembly and comprising a plurality of magnets mounted on a magnet mounting plate and a magnet housing disposed on a surface of the magnet mounting plate to cover and seal the plurality of magnets within the housing.

Sealed linear motor system

A linear motor system is provided includes a coil assembly, a magnet assembly, and a bearing assembly disposed between the coil and magnet assemblies to allow movement of one or both of them. The bearing assembly includes a single bearing rail that can be mounted on either side of the magnet assembly. The rail has elongated recesses that receive bearing elements. A stage structure may be attached to the assembly, such at to the magnet assembly, to move a machine component along the rail.

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.
