1. A method of operating a flux machine at a first frequency and a second frequency, the method comprising:
providing the flux machine, the flux machine including:
a stator;
a plurality of rotors, the plurality of rotors including a first rotor and a second rotor configured to rotate independently about a central axis of the plurality of rotors in a rotary direction;
a plurality of coil assemblies coupled to the stator and;
a plurality of magnet sets coupled to the plurality of rotors, each magnet in each of the plurality of magnet sets being configured to direct magnetic flux in an axial direction or a radial direction, each of the plurality of magnet sets including a first magnet coupled to the first rotor and a second magnet coupled to the second rotor, the first rotor including a first axle configured to rotate about the central axis, the second rotor including a second axle configured to rotate about the central axis, the first magnet of each of the plurality of magnet sets being configured to direct magnet flux in the axial direction toward or away from a respective one of the plurality of coil assemblies, the second magnet of each of the plurality of magnet sets being configured to direct magnetic flux in the radial direction toward or away from the respective one or the plurality of coil assemblies;
driving the first rotor at the first frequency to cause a first current to flow in at least a first one of the plurality of coil assemblies;
driving the second rotor at the second frequency that is different than the first frequency to cause a second current to flow in at least a second one of the plurality of coil assemblies, while maintaining electrical phase synchrony between the first current and the second current.
