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.
Claims20
A moving magnet motor, comprising:
- a cylinder having a cylindrical axis;
- a rider moveable along the cylindrical axis at least partially within the cylinder;
- an electromagnetic field generator configured to generate an electromagnetic field;
- a magnet affixed to the rider, the magnet configured to interact with the electromagnetic field generated by the electromagnetic field generator to impart electromagnetic force to the rider;
- and
- one or more ferromagnetic rods configured to interact with the magnet.
A moving magnet motor, comprising:
- a cylinder having a cylindrical axis;
- a rider moveable along the cylindrical axis;
- an electromagnetic field generator;
- a magnet affixed to the rider, the magnet configured to interact with an electromagnetic field generated by the electromagnetic field generator to impart an electromagnetic force to the rider;
- and
- an alignment assembly including:
- one or more ferromagnetic rods configured to interact with the magnet and/or the electromagnetic field,
- wherein the one or more ferromagnetic rods are positionable to reduce a side load force between the rider and the cylinder.
A method for reducing side load forces on a moving magnetic motor, the method comprising:
- adjusting a circumferential position of one or more ferromagnetic rods relative to a cylindrical axis of a cylinder,
- wherein a rider is moveable along the cylindrical axis of the cylinder via an electromagnetic force, wherein a magnet affixed to the rider is configured to interact with an electromagnetic field generated by an electromagnetic field generator to impart the electromagnetic force to the rider.
