    • The invention relates to an electrical machine, in particular a three-phase alternator (10), having a claw-pole rotor (11) with direct-current excitation, and having a stator winding (16) which is inserted into the slots in a laminated stator core and comprises a plurality of winding systems (16A, 16B), each having three winding sections (R, Y, B) connected to form a star circuit, with the winding systems each being offset through 120° electrical with respect to one another, and with the winding systems also being offset through an electrical angle ε with respect to one another. In order to damp mechanically caused noise in the generator when the machine is used in motor vehicles, it is proposed that the three-phase winding systems (16A, 16B) be connected to one another at their start points (P1, P2) via a coupling element 30 (20).
