Abstract
Provided is a rotating electric machine that allows a stator cooling passage to be formed compactly. A passage of a stator cooling refrigerant is formed by a water jacket fitted and fixed to both ends on a base side which is the flange side and a distal end side of a cylindrical portion of a stator frame on an outer circumference of the cylindrical portion, the stator frame has a difference between a diameter on the base side and a diameter on the distal end side, the diameter on the base side being formed to be larger, and the stator frame and the water jacket are sealed by press fitting and welding on the base side and the distal end side.
