Abstract
An externally excited electric machine may comprise a stator, a rotor, a primary winding, a secondary winding, and electronics. The rotor may be arranged coaxially to and/or in the stator. The rotor may be rotatable relative to the stator about a rotation axis running in an axial direction. The rotor may have a magnetizable hollow-cylindrical core. The primary winding may be guided axially through the core. An electric primary current may flow through the primary winding. The secondary winding may be wound around the core so that an electric secondary current is induced via the primary winding in the secondary winding. The electronic may be connect to the secondary winding for tapping the secondary current.
