Abstract
A rotary vane air motor comprises a rotor, stator and vanes. The rotor has slots for the vanes, and the vanes may move between a retracted position and a contact position in which the vanes contact the cylinder. Each vane may have a longitudinal portion whose shape conforms generally to the slot, and a transverse portion that is radially outside of the slot and extends at least in part in a direction that is transverse to the longitudinal portion and that may be tangential to the perimeter of the rotor at the slot. The shape of the perimeter may be a polygon with rounded corners. The vanes may also include a magnetic portion or a rotating portion.
