US Patent 8368276 Polyphase electrical machine

A polyphase electrical machine, in particular, a polyphase generator, includes a stator which features a core body having a circumferential slot pitch, and a winding configuration having a plurality of windings. It is provided that each winding and each slot of the group of slots that extends over one pole pitch is assigned to one of the phases, and the windings have winding sections that lie in assigned slots and between which, in each case, a winding-head connection is formed, the winding-head connections of different windings being disposed radially in layers relative to each other, and the number of phases being five. A method for producing a polyphase electrical machine is also provided.
