    Abstract: The present application discloses a power actuator for a latch assembly. The power actuator has a motor (70) having a rotatable motor output member (94) and a clutch assembly (50). The clutch assembly has a rotatable clutch output member (48). A stamped, cup-shaped ferromagnetic coil casing (126) has a generally radially extending base wall and an annular side wall extending generally axially from the base wall. An annular ferromagnetic flux intensifying washer (160) is positioned adjacent to the base wall of the coil casing. An annular coil of electroconductive material is operable to selectively generate a magnetic field. The coil (112-118) is disposed within the casing with the side wall extending in surrounding relation with respect to the coi l such that the field generated by the coil flows generally radially through the base wall and generally axially through said side wall. A ferromagnetic armature (120) is in sliding relation with the annular coil and movable between (a) an engaged position wherein the armature couple s the motor output member and the clutch output member together so that energization of the motor rotatably drives the clutch outpu t member and (b) a disengaged position wherein the motor output member and the clutch output member are uncoupled to enable the clutch outpu t member to rotate without resistance from the motor. Selective energizing of the coil effects movement of the armature between th e engaged and disengaged positions thereof.
