Abstract

A rotary vane air motor locking assembly comprises an annular stator housing, first and second end plates, a rotor vane assembly and a locking mechanism. The stator housing extends between first and second axial ends to define a rotor pocket. The first and second end plates are disposed at the first and second axial ends of the stator housing, respectively. The rotor vane assembly is disposed in the rotor pocket and comprises a rotor having an axis of rotation, a plurality of slots disposed within the rotor and a plurality of vanes disposed within the plurality of slots. The locking mechanism is coupled to the second end plate to selectively immobilize rotation of the rotor vane assembly within the annular stator housing by engaging the rotor vane assembly.
