A claw-pole rotor for an electrical machine, in particular a rotary current generator, having two pole wheels ( 26, 27 ), which each carry claw poles ( 28 and 29 , respectively), which each originate in a plate region ( 50 ) and have a pole root ( 53 ), and on a circumference of the claw-pole rotor ( 20 ), claw poles ( 28, 29 ) of the pole wheels ( 26, 27 ) are located in alternation, and located between the claw poles or interstices ( 90 ), and a claw pole ( 28, 29 ) has a radially outward-oriented cylindrical-jacketlike surface ( 43 ), by which a pivot axis ( 65 ) is defined, and a chamfer ( 68 ) extends on the one hand in a circumferential direction and on the other in an edge direction of a claw pole ( 28 and 29 , respectively), wherein the chamfer ( 68 ) has a center portion m in the edge direction that intersects a transition plane ( 59 ) which demarcates the pole root ( 53 ) and the freely projecting part of the claw pole ( 28 and 29 , respectively), and the center portion m amounts to 8/10 of the length, oriented in the edge direction, of the chamfer ( 68 ); and that the claw pole ( 28, 29 ) has a width B<SUB>K</SUB>, oriented in the circumferential direction, and a half width B<SUB>K </SUB>on the cylindrical surface ( 43 ), in a plane of the claw pole ( 28, 29 ) that is vertical to the pivot axis ( 65 ), defines a point (P), and a tangent (T) can be inscribed into this point (P), and an angle of inclination alpha which has a magnitude of between 15° and 25° is enclosed between the tangent (T) and the chamfer ( 68 ) in the plane that is vertical to the pivot axis ( 65 ).
