Abstract (en)
[origin: WO2022129796A1] The invention relates to a coil (20) intended to be inserted in a first and a second notch of a stator (60), the coil (20) being wound in a plurality of successive turns, each turn comprising: - a first half-turn (32a) comprising a first notch portion (34a) configured to be inserted in the first notch of the stator, - a second half-turn (32b) comprising a second notch portion (34b) configured to be inserted in the second notch of the stator, the second half-turns (32b) each being connected to the first half-turn (32a) of the same turn and to the first half-turn (32a) of the following turn by junction portions (40) on each side of the first and second notch portions (34a, 34b), the junction portions (40) of the coil stacking along at least two juxtaposed heads (26a, 26b, 26c, 26d, 26e) extending in mutually parallel junction planes.
