Zusammenfassung:A linear motor including an air gap adjusting device is provided to control an air gap and to prevent a lowering effect of performance thereof by using a non-magnetic gauge. A linear motor including an air gap adjusting device includes a stator(102), a mover(104), and an air gap adjusting device(110). The stator is composed of a fixing structure, a height adjusting unit installed at an upper surface of the fixing structure to control the height, and a plurality of fixed magnetic bodies(102b) arranged on an upper end of the height adjusting unit. The mover is moved along an upper surface of the stator. The mover includes a magnetic body(104b) and has an air gap(G) from the upper surface of the fixing magnetic body. The air gap adjusting device adjusts an air gap between the fixed magnetic body and the movable magnetic body by adjusting the height of the height adjusting unit. A driver applies the force to the height adjusting unit in a direction parallel to a plane of the fixed magnetic body and includes a flexible connecting rod(114).
