摘要:
A system is described in which a magnetic mover includes at least one mover identification device. The system also includes a stator defining a work surface and including an actuation coil assembly and at least one stator identification device operable to interact with the at least one mover identification device. One or more sensors are used to sense a position of the first magnetic mover. One or more stator driving circuits are used to drive the actuation coil assembly to thereby move the first magnetic mover over the work surface. The first magnetic mover includes one or more magnetic components positioned such that interaction of one or more magnetic fields emitted by the one or more magnetic components with one or more magnetic fields generated by the actuation coil assembly when driven by the one or more stator driving circuits enables movement of the first magnetic mover in at least two degrees of freedom.
