Abstract
Provided is a stator for rotating electric machine that enables reduction in imbalance of compression stress on a stator core between a thin portion due to formation of a cooling passage of a frame and a thick portion where there is no cooling passage. This stator for rotating electric machine includes: a stator coreformed in a cylindrical shape; and a framehaving an inner circumferential side to which the stator coreis fitted and fixed with a predetermined interference, and an outer circumferential side on which a passagefor cooling fluid for cooling the stator coreis formed, wherein the interference at a thin portion A due to formation of the cooling passage, of the frameis greater than the interference at a thick portion B where there is no cooling passage
