Abstract
An electrically excited synchronous machine, comprising a stator having a stator housing with at least one axial end-face bearing shield and a stator coil for generating a magnetic stator field, a rotor having a rotor shaft rotatably supported at least on the bearing shield about a rotational axis and a rotor coil for generating a magnetic rotor field, and an energy transmission system having an energy transmitter for transmitting electric energy to the rotor coil, wherein the bearing shield contains at least one coolant channel and has a coolant inlet and a coolant outlet such that the bearing shield is actively cooled by a coolant conducted through the coolant channel, and the energy transmitter has at least one component fixed to the stator and arranged in or on the bearing shield so as to transfer heat.
