Abstract: This paper proposes new-shaped pole pieces for a
low-speed rotor of a magnetic-geared generator, which unify a magnetic gear
and a generator and can realize downsizing and maintenance-free operation
for large output power machines such as a 2-MW class used for wind power
generations. The concept of the new-shaped pole pieces is described, and its
effectiveness is verified by finite element analysis and measurements on a
prototype downsized in 1-kW class.
Keywords: Magnetic-geared generator, fixing method, pole piece
