Abstract
An electromagnetic camshaft adjusting device has an armature unit, which can be moved relative to a yoke and core unit by energizing a stationary coil unit and which is designed to carry out an axial actuating movement and to exert a correspondingly axially directed actuating force on a rotating internal combustion engine camshaft by a slider unit interacting with the armature unit. The yoke and core unit is mounted such that it can rotate relative to the coil unit and provides a receptacle for the armature unit that is guided such that it can move axially in the yoke and core unit and has the slider unit firmly seated thereon.
