The invention provides a polyphase armature ( 13 ) for a rotary electrical machine, comprising a body ( 14 ) carrying a plurality of phases ( 20 to 25 ), each of which comprises, firstly, an input (E 1 to E' 3 ) and an output (S 1 to S' 3 ), each of which is part of an electrically conductive input element and output element respectively, and, secondly, electrically conductive elements ( 37 ) for connecting the input of a phase to the output of a phase and constituting a winding having at least two coils per phase, together with at least one first electrically conductive inversion element ( 38, 338 ) for reversing the circumferential direction of the current in the winding, the said first inversion element being interposed electrically between the two coils, at least one phase winding being provided with at least one electrically conductive second inversion element ( 138, 238 ) for reversing the circumferential direction of the current in the said phase winding, and the electrically conductive output element of the said winding being connected in the electrical circuit that includes the two coils and the two electrically conductive inversion elements. The invention also provides a method of making such an armature. Application: a stator for a motor vehicle alternator.
