Abstract
The invention mainly concerns a coiling procedure of a stator for a multiphase electrical rotating machine: the said stator comprising grooves, each intended to take up an uneven number of conductors of a coil, the said coil comprising two systems, each comprising one group of conductors (C-C, C'-C′) respectively, the said procedure comprises stages of installation of the conductors (C-C, C′-C′) into the said grooves, repeated in order to form a coil comprising several turns (S-S) completed alternately according to a first direction of rotation (K) and according to a second direction of rotation (K) opposite the first direction of rotation, with the characteristic that at least two changes of direction of rotation (CH-CH) from one turn to the other are carried out in different angular zones.
