Original Kurzfassung:
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.
