Abstract
In accordance with various embodiments of the present disclosure, an orbital magnetic gear includes a gear shaft. The orbital magnetic gear also includes a first stator magnet ring fixed at a. first axial position along the gear shaft and a second stator magnet ring fixed at a second axial position along the gear shaft and adjacent the first stator magnet ring. The orbital magnetic gear further includes a rotor magnet ring rotatably coupled to the gear shaft. The rotor magnet ring is canted relative to the gear shaft and to the first and second stator magnet rings.
