A linear motor system includes a discontinuous linear motor (1) and motor control device (2). The discontinuous linear motor (1) includes a mover (4) and a plurality of individual motors (3) spaced from each other along a movement path of the mover (4). Each of the individual motors (3) functions as an armature on a primary side of one independent linear motor. A sensor (15), acting as a linear scale, is disposed for each individual motor (3) and detects a position of the mover (4). The motor control device (2) includes a plurality of individual motor control units (6) and a multiple unit controller (7) to comprehensively control them. The individual motor control units (6) control the individual motors (3) disposed in curved path sections, and each of them includes a curved-line correspondence corrector (9) to correct a detection value obtained from the sensor (15) according to a relationship between a curved line of the path and a position of the sensor (15). |
