Abstract
An axial flux magnetic geared machine includes a high speed magnetic rotor and a low speed magnetic rotor maintained in a spaced relationship from the high speed magnetic rotor. A modulating structure is disposed between the high speed magnetic rotor and the low speed magnetic rotor. A stator is disposed in a radially central bore of one or more of the high speed magnetic rotor, the low speed magnetic rotor, and the modulating structure.

An axial flux magnetically geared machine, comprising:
- a high speed magnetic rotor;
- a low speed magnetic rotor maintained in a spaced relationship from the high speed magnetic rotor;
- a modulating structure disposed between the high speed magnetic rotor and the low speed magnetic rotor, so as to modulate a magnetic field of at least one of the high speed magnetic rotor and the low speed magnetic rotor;
- and
- a stator disposed in a radial central bore of the modulating structure and at least one of the high speed magnetic rotor and the low speed magnetic rotor.
A method of forming an axial flux magnetically geared machine, the method comprising:
- arranging a high-speed magnetic rotor in a spaced relationship from a low-speed magnetic rotor;
- positioning a modulating structure between the high-speed magnetic rotor and the low-speed magnetic rotor, so as to modulate a magnetic field of at least one of the high-speed magnetic rotor and the low-speed magnetic rotor;
- and
- positioning a stator in a radial central bore of the modulating structure and at least one of the high speed magnetic rotor and the low speed magnetic rotor.
An axial flux magnetically geared machine, comprising:
- a high speed magnetic rotor;
