Abstract: A linear motor system includes a stator, a mover, and a controller. The stator includes a plurality of armature coil units arranged so as to be spaced apart from one another at certain intervals. The mover includes a permanent magnet. The controller is configured to sequentially select, as a power-feeding target, an armature coil unit opposing the mover from among the plurality of armature coil units, perform, for the power-feeding target, computation for power-feeding control on the basis of a speed command, and sequentially feed power to the armature coil unit. The controller includes a power-feeding-switching compensation function of performing switching compensation when the power-feeding target is switched to a next armature coil unit.

Abstract: A gantry drive system includes: a first motor configured to drive a driving object along a first axis; a second motor configured to drive the driving object along a second axis parallel with the first axis; and a motor control system configured to control the first and second motors. The motor control system includes a mode switch that performs a switching between a first control mode in which a position of the driving object on each of the first and second axes is individually controlled while reducing an inter-axis positional deviation between the first and second axes, and a second control mode in which a rotational state of the driving object is controlled while controlling a position of the driving object, based on detected positions of the driving object on the first and second axes.
