ELECTRICAL MACHINE, IN PARTICULAR A THREE-PHASE ALTERNATOR

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 ( 16 A, 16 B), 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 epsilon 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 ( 16 A, 16 B) be connected to one another at their start points (P 1 , P 2 ) via a coupling element 30 ( 20 ).
