Patent ID: 10931168

Abstract:
A shrouded bladed-rotor for use as a rotor of an electrical generator incorporates a plurality of blades and an annular magnetically-permeable yoke concentric with an associated axis of revolution. An even-numbered plurality of permanent magnets are operatively coupled to an outer surface of the annular magnetically-permeable rotor yoke, the latter of which comprises either a shroud of the shrouded bladed-rotor or a ring of magnetically-permeable material encircling the shroud. The North-South axis of each permanent magnet is substantially radially oriented with respect to the axis of rotation, and North-South orientations of every pair of circumferentially-adjacent permanent magnets of the plurality of permanent magnets are opposite to one another. A non-magnetic magnet-retaining-ring encircling the plurality of permanent magnets has sufficient hoop strength to retain the plurality of permanent magnets on the annular magnetically-permeable rotor yoke during intended operation of the electrical generator.
