A voltage regulator having overvoltage protection which is situated in a vehicle electrical system between the generator that is situated in a first voltage level and a battery that is situated in a second voltage level. A generator is used as a generator whose control voltage is freely selectable within specifiable limits. The voltage regulator, which is embodied as an in-phase regulator, makes available a regulated voltage on the output side, which is used for supplying the usual vehicle electrical system users as well as for charging the battery. The in-phase regulator is furnished with an electronics system or an intelligence which includes a microprocessor and which evaluates supplied data with regard to voltages, currents or load breakings and which specifies response criteria, and, upon the reaching of certain response criteria, initiates the measures which then become necessary.

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 &#x3b1; which has a magnitude of between 15&#xb0; and 25&#xb0; is enclosed between the tangent (T) and the chamfer () in the plane that is vertical to the pivot axis ().
