ELECTRIC GENERATOR

The invention relates to an electric generator (1), in particular an alternator for a motor vehicle. The electric generator (1) has a rotor (2) and a stator (3), having at least two claw poles (4, 5), which are fixed on the shaft (6) and have a plurality of claw pole teeth (4a, 5a). The claw pole teeth (4a, 5a) form an outer circumference (7) of the rotor (2). Arranged between the claw poles (4, 5) there is at least one excitation coil (8) for generating a magnetic field that alternates on the claw pole teeth (4a, 5a) on the outer circumference (7) of the rotor (2). A slipring arrangement (11) has a sheathing region (17), which sheaths the shaft (6) and extends axially, at least in regions. The slipring arrangement (11) has two sliprings (12a, 12b), which are arranged, at a distance from the rotor (2), on the sheathing region (17) and go around the shaft (6). The slipring arrangement (11) additionally has two electrical conductors (14a, 14b), which are sheathed, at least in regions, by the sheathing region (17) and via which the sliprings (12a, 12b) are electrically contacted to the excitation coil (8).. According to the invention, the slipring arrangement (11) has at least one protective ring projection (19) and a rotor bearing (10a) is fixed in a form-fitting or in a press-fitting on the protective ring projection (19) of the slipring arrangement (11).
