Abstract (en)

[origin: WO2007141230A1] An alternator is proposed for motor vehicles, having a rotor (20) whose poles (32) are in the form of claw-type poles. In order to improve the design options for the stator of the machine, its polyphase winding is in the form of a fractional-slot winding, thus creating a large number of additional options in particular for selection of the number of slots (N), thus not only considerably simplifying and reducing the cost of manufacture, but also at the same time making it possible to improve the electrical characteristics.
