[Prior Art] A linear induction motor having a configuration in which an induction motor is cut open and deployed has a structure in which a primary coil on the power supply side and a secondary conductor on the power supply side are opposed via a gap. A thrust is generated by a traveling magnetic field created by passing an alternating current to the primary side and an eddy current generated on the secondary side conductor by the traveling magnetic field. On the secondary side, a conductor and a magnetic material are often used in combination. Either the primary side or the secondary side can be movable, and is used for a pallet transport device or the like.
