1. A linear motor system comprising:
a plurality of armatures that are disposed along a movement path of a mover continuously or discretely;
a detector that detects position information of the mover in the movement path;
zone controllers that are provided to a plurality of unit zones of the movement path in one-to-one correspondence and control the armatures disposed on the unit zones, respectively; and
an integrated controller that collectively supplies an identical traveling instruction relating to the movers to the plurality of zone controllers provided to the movement path based on the position information detected by the detector and controls the plurality of zone controllers, wherein
the zone controllers determine whether the mover to be driven is present in the related unit zones based on the traveling instruction, and control the plurality of armatures based on determined results.
