Abstract
A motor is configured to apply a rotational force to a wheel that includes a rim rotatably mounted to an axle about a first axis. The motor has a rotor coupled to the rim. The rotor has an interior cavity and a plurality of radial slots formed therein. A cylindrical stator is disposed within the cavity and has a second axis offset from the first axis. The stator is fixed in rotation relative to the axle. The motor further includes a plurality of vanes, each vane being slidably disposed within one of the plurality of radial slots. A compressed gas source is in fluid communication with the cavity and selectively provides compressed gas to the cavity to rotate the rotor.

A motor for applying a rotational force to a wheel, the wheel having a rim rotatably mounted to an axle about a first axis, the motor comprising:
- a rotor coupled to the rim and having an interior cavity and a plurality of radial slots,
- a cylindrical stator disposed within the cavity and having a second axis offset from the first axis, the stator being fixed in rotation relative to the axle;
- a plurality of vanes, each vane being slidably disposed within one of the plurality of radial slots;
- and
- a compressed gas source in fluid communication with the cavity, wherein the compressed gas source selectively provides compressed gas to the cavity to rotate the rotor.
