Abstract
The disclosed system may include (1) a subassembly including (a) conductive coils having portions oriented along a first direction, and (b) a body that holds the coils such that the portions are aligned along a second direction orthogonal to the first direction, (2) a structure that generates a magnetic field directed through at least one coil along a third direction orthogonal to the first and second directions, (3) a commutation controller that (a) receives a current command indicating a total amount of current to provide to the coils, and (b) determines, based on a present location of the body along the second direction relative to the magnetic field, a portion of the total amount to supply to each coil, and (4) a coil driver for each coil, where each coil driver supplies the portion of the total amount to the corresponding coil. Various other embodiments are also disclosed.
