PROBLEM TO BE SOLVED: To provide a rotary electric machine that can improve cooling performance for a coil end of a stator.SOLUTION: A rotary electric machine includes: a stator which is arranged in a casing and comprises a stator core and a stator coil; a rotor which is arranged on an inner peripheral side of the stator via a gap, and comprises a rotary shaft, a rotor core, and a rotor coil; an end cooling air space partition body which forms an end cooling air space at an end of the stator; an axial flow fan which is mounted on the rotary shaft at a position of the end cooling air space partition body on the side of the rotary shaft, and sucks cooling air into an end cooling air space and blows the air to an outer peripheral portion of the stator; an air cooler which is arranged at the outer peripheral portion of the stator, and cools the cooling air blown to the outer peripheral portion of the stator; an isolation member which is arranged on an outer peripheral side of an end of the stator, and isolates the end cooling air space and the air cooler from each other; and an air vent which is formed in the isolation member. |
