Title: Magnetic-Geared Bearingless Motor Unit with Central Exterior Output
Keywords: bearingless motor, high speed, magnetic gear, system design

Abstract: This paper presents a novel design concept for a magnetically geared motor, where the high-speed shaft of a magnetic gear is levitated and driven by two bearingless motors. This enables high input speeds and, thus, a device with high power density. As a magnetic gear can realize high gear ratios within one stage, the motor speed can be transformed to a reasonable output speed. Besides a discussion of the proposed concept, the design aspects of the bearingless motor(s), the magnetic gear, and their interaction on a system level are presented. Also, finite-element based optimizations of the components will be conducted.
