▣ Title: Combined Winding Bearingless Systems
▣ Affiliation: Johannes Kepler University
▣ Date: 2021. 9. 10.(Fri) 14:00
▣ Venue: Online(Zoom)
▣ Host: Prof. Junyoung Yoon
▣ Abstract
In the talk, bearingless motors and combined winding structures therein are discussed. These drive systems feature more than three phases and motor torque and suspension forces are simultaneously generated in all windings. Phase currents are superposed of drive torque and suspension force current components. The advantages are reduced copper loss, simpler manufacture and increased efficiency. Bearingless motors of such kind creating axial forces and others creating radial forces are outlined. Special consideration is given to the bearingless slice motor. These devices provide a reduced number of active position regulations, as several degrees of freedom are passively stabilized. Limiting the number of actively regulated axes results in cost down and simplification. The control strategy for such combined winding bearingless motors is addressed and several system developments (e.g, towards high speed and high torque) are shown. Finally, also the implementation of magnetic levitation in textile spinning devices is exemplified.
