Abstract
The invention relates to 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 for rotating the camshaft relative to the drive gear, the electric motor having two concentrically arranged rotors, of which the one is connected to the camshaft and the other to the drive gear. Simple and safe adjusting is achieved by having a first coil arrangement non rotatably linked to one of the rotors and electromagnetically interacting with a stationary coil arrangement in order to induce or to transmit the energy needed for the operation of the electric motor.
