The invention relates to an electrical machine, especially an alternator () comprising a stator winding () with a total of seven phase conductors (Pto P) which are interconnected in series at the same electrical angle (a). The aim of the invention is to dampen magnet noise and to increase machine performance. For this purpose, at least every other electrically subsequent phase conductor (P) is skipped when the phase conductors (Pto P) are connected in series.

Electrical machine, in particular an alternator

An electric machine, in particular an electrically excited claw pole generator for a motor vehicle, is provided, having a stator winding, the phase terminals of which may be connected in the manner of a pentagram to a rectifier system. The stator winding has a five-phase design, phase terminals situated in adjacent slots being interconnected at least once. All of the phase terminals may be interconnected are situated in adjacent slots.

Electric 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.

Polyphase electrical machine

The invention relates to a five-phase electric generator (), in particular for a motor vehicle, said generator comprising five electric branches () for five different phases, the latter being electrically connected at interconnection points (). The electric angle (&#x3b1;) ranges between 25&#xb0; and 36&#xb0; at said interconnection points ().
