Abstract
A cam phasing control motor assembly, including: an electric motor with a hollow drive shaft; an actuating pin passing through the hollow drive shaft; an engagement feature; and a displacement assembly. For a camshaft locking mode: the displacement assembly displaces the actuating pin in a first axial direction to non-rotatably connect the engagement feature with a bolt non-rotatably connected to a camshaft; and the camshaft is arranged to non-rotatably connect to an input gear for a gearbox phasing unit, the input gear arranged to receive torque from an engine. For a phase adjusting mode: the displacement assembly displaces the actuating pin in a second axial direction, opposite the first axial direction, to disconnect the engagement feature from the bolt; and the camshaft is arranged to rotate with respect to the input gear.
