Abstract
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.
