Abstract

See full text

A pneumatic motor includes a stator having a stator inner wall including a dwell region and a rotor eccentrically disposed within the stator. The rotor is configured to rotate about the axis of rotation and includes a plurality of vanes disposed around the rotor. Each vane of the plurality of vanes is configured to slide within a respective slot formed in the outer surface of the rotor between a fully retracted position and a fully extended position as the rotor rotates about the axis of rotation to maintain contact with the stator inner wall. The stator inner wall has a radius relative to the axis of rotation that is substantially constant within the dwell region so that vanes of the plurality of vanes are in the fully extended position within the dwell region.
