Self-ventilated open traction motor and rail vehicle equipped with such a motor

Self-ventilated open traction motor comprising:

• a stator,
• a rotor separated from the stator by an air-gap,
• a casing extending along a rotation axis of a shaft of the rotor between a first end and a second end and comprising an air inlet flange at the first end and an air outlet flange at the second end,
• at least one stator cooling channel in fluidic connection with at least one stator air inlet of the air inlet flange and at least one air outlet of the air outlet flange,
• the air-gap being in fluidic connection with at least one rotor air inlet of the air inlet flange and with the at least one air outlet,
• a main fan configured for circulating air from the at least one rotor air inlet and from the at least one stator air inlet towards the at least one air outlet, being characterized in that the motor further comprises:
• for cooling the rotor comprising at least one rotor cooling channel provided in the rotor, and
• for circulating air contained in the closed air pathway.
