Abstract
The disclosed system may include (1) a conductive coil, where at least a portion of the coil is oriented along a first direction and orthogonal to a second direction, (2) a magnetic field generation structure that generates a magnetic field through the coil along a third direction orthogonal to the first and second directions, (3) a detection subsystem that determines a location of the coil relative to the field, (4) a force-to-current converter that (a) receives a force command to alter a relative location of the coil and the field, and (b) issues, in response to the force command, a current command based on the location of the coil relative to the field, and (5) a coil driver that generates, in response to the current command, current in the coil to generate a force between the coil and the field along the second direction. Various other embodiments are also disclosed.
