Abstract

An alternator for motor vehicles, having a rotor, whose poles are developed as claw-poles. In order to improve the design options of the stator of the machine, its multiphase winding is developed as a fractional-slot winding, whereby, in particular with respect to the selection of the number of slots, many additional options are created, by which both the production is made clearly simpler and less costly and, at the same time, the electrical properties are able to be improved.
