Abstract
A camshaft phaser, including: a stator to receive rotational torque from an engine and including a radially inwardly facing surface and a slot in the radially inwardly facing surface; a rotor to non-rotatably connect to a camshaft, to be connected to an electric motor and including a first radially outwardly extending protrusion; and a spring non-rotatably connected to the stator and including a first portion disposed in the slot. The electric motor is arranged to rotate the rotor with respect to the stator. In a first circumferential position of the rotor with respect to the stator: no portion of the spring is disposed in the indent; and a second portion of the spring extends radially inwardly past the radially inwardly facing surface. In a second circumferential position of the rotor with respect to the stator, the second portion of the spring is disposed in the indent.
