A cam phaser () dynamically adjusts a rotational relationship of a camshaft () of an internal combustion engine with respect to an engine crankshaft operably connected with a phaser sprocket (). The cam phaser () can include a planetary gear assembly having a ring gear () driven by the phaser sprocket (), a planetary gear carrier () connected to the camshaft (), a sun gear (), and at least one rotatable planetary gear (). The cam phaser () can include a sprocket housing () connected with the phaser sprocket () and operable for connection with the ring gear (), a cover plate () secured to the carrier (), and a adapter () connected between the sun gear () and an electric motor () for changing an angular position of the sun gear () and adjustably varying a cam phase position of the camshaft () relative to the crankshaft.
