A technique facilitates control over the actuation of a device by utilizing a rotor and a corresponding stator system. The technique employs a rotor and a corresponding stator component in a progressive cavity type system. The rotor and corresponding stator component are mounted such that rotational and/or axial motion may be imparted to at least one of the rotor or stator components relative to the other component. The controlled rotation may be utilized in providing controlled motion of an actuated device via the power of fluid moving through the progressive cavity type system.
