GAS TURBINE ENGINE WITH MAGNETIC GEARBOX

摘要

A magnetic gearbox for use in a gas turbine engine includes an inner rotor assembly, a stator assembly, and an outer rotor assembly. The inner rotor assembly includes a first plurality of permanent magnets and an inner rotor. The outer rotor assembly includes an outer rotor and a second plurality of permanent magnets. Each of the inner and outer rotors include a plurality of slots to receive an attachment portion of each of the first and second plurality of permanent magnets to secure the plurality of magnets relative to the rotors during rotation.

1. A magnetic gearbox for use in a gas turbine engine, the magnetic gearbox comprising:
a stator assembly including a plurality of stator poles arranged around a central axis, an inner rotor assembly located radially inward of the stator assembly and mounted for rotation relative to the stator assembly about the central axis, the inner rotor assembly including an inner rotor and a first plurality of permanent magnets coupled to the inner rotor, and an outer rotor assembly located radially outward of the stator assembly and mounted for rotation relative to the stator assembly about the central axis, the outer rotor assembly including an outer rotor and a second plurality of permanent magnets coupled to the outer rotor, wherein the inner rotor of the inner rotor assembly is formed to include a first plurality of slots that each receive an attachment portion of one of the first plurality of permanent magnets coupled to the inner rotor so that the first plurality of permanent magnets coupled to the inner rotor are held in place relative to the inner rotor during rotation of the inner rotor assembly.
