Abstract
A device for adjusting the phase angle of a camshaft of an internal combustion engine with a drive gear for driving a camshaft accommodated in a coaxial arrangement relative to the camshaft and with an electric motor communicating with the camshaft via a Harmonic Drive having a roller bearing with an elliptical inner ring, an externally toothed, flexible gear arranged on said roller bearing and a rigid, internally toothed gear engaging the externally toothed gear. A simple and compact structure is achieved by providing the electric motor with a housing which is rigidly connected to the drive gear and which is at least partially arranged therein and by also providing the electric motor with a rotor configured as a disk rotor accommodated in a slot between two housing halves of the electric motor.
