Abstract
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.
