Abstract
This paper presents a synchronous planar motor prototype with a cross winding system for high dynamic motion in two feed axes. The approach uses a synchronous permanent magnet planar motor, where the magnets are located in the stationary part and the coils are mounted on one moving yoke. A cross winding technology with concentrated windings is implemented to realize a compact feed drive for machine tools. An experimental setup was used to obtain the characteristic behavior of the inductance and disturbance- and feed-force deviation of the drive. Disturbance-forces like cogging- and detent-forces occur due to parasitic effects between the permanent magnets and the iron based yoke. It is theoretically and experimentally shown, that both winding layers marginally interact. Based on the identified characteristics, two independent cascade control systems are developed. The disturbance-force is compensated by a feedforward control. The performance of this first prototype is finally shown in a circular milling setup.
