A turbogenerator (20) comprises a rotor (13) and a stator (14), which stator (14) has a polyphase winding, the terminals of which are arranged as generator terminals (U1, . . . ,W2) in a terminal arrangement (25) at the turbogenerator (20) to be connected to a neutral point (26) and to bus bar connections (S1, . . . ,S3). The terminal arrangement (25) is configured such that the phase sequence can be changed in a simple way by changing the connecting scheme at the terminal arrangement (25).
