Magnetic Geared Electrical Machine, Electric Power Generation System, And Drive System

Abstract: This magnetic-geared electrical machine includes: a stator; a magnetic pole piece rotor including a plurality of magnetic pole pieces disposed inward in a radial direction from the stator; an inner rotor that includes a plurality of rotor magnets, is disposed inward in the radial direction from the plurality of magnetic pole pieces, and rotates at a faster speed than the magnetic pole piece rotor; and a fan for cooling at least one of the stator, the magnetic pole piece rotor, and the inner rotor. The magnetic pole piece rotor further includes a power transmission shaft that is disposed on one side in the axial direction with respect to the plurality of magnetic pole pieces, and that is for transmitting motive power to and from an external device. The fan is provided on the inner rotor, on the side opposite the power transmission shaft in the axial direction, across the rotor magnets.
