Patent ID: 8796959

Claim:
A linear motor system comprising: a linear motor; and a motor control device to control the linear motor; wherein the linear motor is a discontinuous linear motor including: a mover including permanent magnets; a plurality of individual motors spaced from each other along a movement path of the mover, each of the plurality of individual motors defining an armature on a primary side of one independent linear motor and including coils of different phases, respectively, aligned in a straight line direction; and a sensor to detect a position of the mover, the sensor arranged to act as a linear scale and being disposed, for each individual motor, along the straight-line direction corresponding to a coil-aligned direction; the motor control device includes: a plurality of individual motor control units, each disposed relative to a set of the individual motor and the sensor, to control the individual motor in the set; and a multiple unit controller programmed to send a position command to the plurality of individual motor control units; and each of the plurality of individual motors is disposed as a stationary side.
