Abstract
A multi-rotor electric machine includes a first rotor, a stator, and a second rotor. The stator is disposed concentric with the first rotor and is disposed radially outward from the first rotor. The stator has a first plurality estate or windings disposed proximate first stator teeth of the stator. The stator has a second plurality of stator windings disposed proximate second stator teeth of the stator. The second rotor is disposed concentric with and is disposed radially outward from the stator. The second rotor is rotatable relative to the first rotor.
