<p>The electrical machine (10) comprises a first rotor core (13), with a first rotor winding (14), a first stator core (16) with a first stator winding (17), an excitation device (18) for supplying current to the first rotor winding (14). The excitation device has a second rotor core (19) with a second rotor winding (20), the second rotor core (19) being connected to the first rotor core (13) in a fixed rotational relationship, and a second stator core (21) with a second stator winding (22). The second rotor winding (20) and the second stator winding (22) are multi-phase windings, and the first and second rotor windings (14, 20) are connected to one another.</p> |
