| 摘要 | For ensuring high-precision control of a planar motor (1) comprising a magnet (2) and j coils (3), j=l ...N, wherein currents T7 can flow through the coils (3) such that a force and a moment are generated that interact with the magnet (2), it has been proposed to determine force and moment needed to change the relative position of magnet (2) and coils from a present position to a desired position, and then to determine the currents T7 necessary for generating this force and moment in the computing means (43) of the control unit (4) of the electric motor (1). The coil currents are then regulated accordingly with regulating means (44). The relative position of magnet (2) and coils (3) is measured with measuring means (5) and fed into the first input means (41) of the control unit (4). | ||||||
