ABSTRACT:
A lockable motor assembly for use in a well bore comprises a stator, a rotor rotatably mounted within the stator, and a selectively removable flow restriction means. The lockable motor assembly may further, comprise holding means for rotationally fixing the rotor to the stator. The flow restriction means limits the flow rate of fluid downstream of the rotor, thereby substantially balancing hydraulic pressure above and below the stator.
