摘要： A lockable motor assembly (1) for use in a well bore comprises a PDM motor (2) having a rotor (4) and a stator (3). A locking member (12) has a splined projection (13) which is received within a splined recess (14) of the rotor and external splines (15) which mate with splines provided on a sub (5) connected to the stator. The components are held in this configuration by a shear ring (23) until the fluid pressure within a chamber (28) defined between the locking member (12) and the sub (5) is sufficient to cause the shear ring to shear. The locking member (12) may then move out of the engagement with the rotor to free the motor for operation. The locking member is held in this position by a ratchet mechanism (35).
