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