Abstract:
A linear motor system includes a discontinuous linear motor and motor control device. The discontinuous linear motor includes a mover and a plurality of individual motors spaced from each other along a movement path of the mover. Each of the individual motors functions as an armature on a primary side of one independent linear motor. A sensor, arranged to act as a linear scale, is disposed for each individual motor and detects a position of the mover. The motor control device includes a plurality of individual motor control units and a multiple unit controller to comprehensively control the individual motor control units. The individual motor control units control the individual motors disposed in curved path sections, and each of the individual motor control units includes a curved-line correspondence corrector to correct a detection value obtained from the sensor according to a relationship between a curved line of the path and a position of the sensor.
