Title:
MAGNETIC GEARED ROTARY MACHINE, POWER GENERATION SYSTEM, AND MAGNETIC POLE PIECE ROTOR
Document Type and Number:
WIPO Patent Application WO/2022/210237
Kind Code:
A1
Abstract:
A magnetic pole piece of this magnetic geared rotary machine includes an outer edge and one or more inner edges. The outer edge forms, in a radial cross-section of the magnetic geared rotary machine, a first surface of the magnetic pole piece and a second surface of the magnetic pole piece, wherein the first surface faces a rotor across a first air gap, and the second surface faces a stator across a second air gap. The inner edges are located between the first and second surfaces in the radial direction so as to be surrounded by the outer edge and define one or more voids inside the magnetic pole piece. In the radial cross-section, a first radial distance between the first surface and the void is shorter than a second radial distance between the second surface and the void.
