Abstract
A linear transport system includes: a stator module including an iron core that includes a plurality of teeth and a coil wound around the iron core; a movable element that includes a plurality of identical magnets disposed on a side surface parallel to a moving direction, and is propelled by an electromagnetic force from the coil; and a motor drive control device that controls the movable element by supplying an independent current of single-phase AC individually to the coil included in the stator module. When Lm is a magnet pitch that is a pitch of the magnets disposed in the movable element, and Lt is a tooth pitch that is a pitch of the teeth, 1.3≤Lm/Lt≤1.4 is satisfied.
