Abstract
A system can comprise a screw and a nut, which are configured to move relative to each other. Each of the screw and the nut components can comprise one or more magnets configured to exert a repulsive force on one or more magnets of the other component as a result of the relative motion. Interactions between the one or more magnets of the screw and the one or more magnets of the nut can allow for conversion between linear motion and rotary motion. One or more tools can be used to aid in manufacturing the screw and/or the nut. In some embodiments additional components can aid in maintaining alignment of the screw and the nut.
