Planar motions for future small machine tools and for automation with strokes up to approximately 20×20 mm² can advantageously be realised with electrodynamic planar direct drives. Integration of the position control and power electronics thereby results in particularly compact devices. In this contribution, the design and characteristic of a built demonstrator of such a novel drive unit are shortly described in the beginning. It features a medium precision, low-cost position sensor system. A mathematical model for the planar direct drive is shown. A flatness based state space controller for transition between desired rest positions has been developed. Finally the achieved dynamics and accuracy are shown.
