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.
