Title:Design and Sizing Relations for a Novel Bearingless Motor ConceptAuthor(s):Walter Bauer,  Wolfgang AmrheinAbstract:A new bearingless motor concept is presented in this paper. The proposed Axial Force/Torque motor is able to generate axial bearing forces and drive torques concurrently with one common winding system. The end-windings of a concentrated air-core coil winding can produce forces in the axial direction, if the rotor magnet system features a special magnetization pattern, that prevents the cancellation of the end-winding forces. Simple analytic models, that can clearify the influence of the motor main dimensions on its force and torque generation capability are presented.Booktitle:International Conference on Electrical Machines and Systems 2011, 20. - 23.08.2011, Bejing/ChinaEditor(s):ICEMS2011ISBN:978-1-4577-1044-5Page Reference:page 1-6, 6 page(s)Publishing:8/2011
