A separately excited synchronous machine (1b1k) with an excitation circuit on the side of the rotor includes an excitation winding (3) and a power supply for the excitation winding (3) as well as a switching element (8a, 8e) for connecting the power supply to the excitation winding (3). Further, the synchronous machine (1b1k) comprises a first stator-side primary winding (5a5f) and a first rotor-side secondary winding (6a6f). Moreover, the synchronous machine (1b1k) may comprise a) a tap of the first rotor-side secondary winding (6d) connected to a control element (9a, 9e) of the switching element (8a, 8e) or b) a second rotor-side secondary winding (14d), which is coupled to the first stator-side primary winding (5a5f) and connected to a control element (9a, 9e) of the switching element (8a, 8e). |
