Abstract:
A linear motor control apparatus has: a plurality of coil units; a plurality of position detecting units for detecting positions of a plurality of trucks which move over the plurality of coil units; a plurality of deviation calculating units for operating deviation information as differences between the detected truck positions and a target position of the detected truck; a plurality of position control units for operating current control signals based on the deviation information; a plurality of current control units for supplying driving currents to the coil units based on the current control signals; and a switching unit for switching the position control units to which the deviation information is transmitted or switching the current control units to which the current control signals are transmitted.
