Abstract:
A linear motor control apparatus includes a plurality of coil units which are continuously arranged, a plurality of position detecting units configured to detect positions of a first truck and a second truck which move over the plurality of coil units, and a first deviation calculating unit configured to arithmetically operate deviation information as differences between values of the plurality of position detecting units and a target position. In addition, a first position control unit arithmetically operates current control signals on the basis of the deviation information, a first current control unit supplies driving currents to the plurality of coil units on the basis of the current control signals, and a switching unit outputs the values of the plurality of position detecting units for the first truck to the first position control unit and outputs the values of the plurality of position detecting units for the second truck to a second position control unit.
