Coiling procedure for the stator of an electrical rotating machine, and corresponding coiled stator

A stator for a multiphase electrical rotating machine comprising grooves, each intended to take up an uneven number of conductors of a coil:

• the coil comprising:
• two systems each comprising one group of conductors respectively,
• several turns completed tangentially alternating according to a first rotational direction, then according to a second rotational direction opposite the first rotational direction,
• wherein at least two changes of rotational direction from one turn to the other are situated in different angular zones.

A method for coiling of a stator for a multiphase electrical rotating machine,

• wherein the stator comprises grooves each intended to take up an uneven number of conductors of a coil, the coil comprising two systems each comprising one group of conductors respectively, and
• wherein the method comprises:
• repeating stages of installation of the conductors into the grooves, so as to form a coil comprising several turns completed tangentially alternating according to a first rotational direction and according to a second rotational direction opposite the first rotational direction,
• wherein at least two changes of rotational direction from one turn to the other are carried out in different angular zones, and
• wherein each of the at least two changes of the rotational direction is in a tangential direction of the stator.
