Abstract: The invention concerns a stator of an electric rotating machine, the stator comprising a housing, a stator core (1), windings, and a distribution ring (2), the stator core (1) having inner and outer (11) longitudinal grooves, the outer longitudinal grooves (11) and the housing forming axial cooling channels configured to channel a coolant; the windings being located within the inner longitudinal grooves and forming at each end of the stator core (1) protruding windings ends, the distribution ring (2) being contiguous to the stator core (1) and comprising recesses (21) extending the outer longitudinal grooves (11), the recesses (21) being configured to guide the coolant from the outer longitudinal grooves (11) towards the protruding windings ends, such that the coolant flows over the protruding windings ends under the effect of gravity and/or due to the pressure of the coolant to cool the protruding windings ends.
