Abstract:
A rotary electric machine includes: an annular cooling oil channel that is configured inside an externally mounted frame so as to face axially toward coils that are arranged in an annular shape and such that a surface that faces the coils is made into an opening; an oil pump; a nozzle that sprays cooling oil that is conveyed under pressure from the oil pump into the cooling oil channel from above; and a plurality of oil flow direction changing projections that are respectively disposed inside the cooling oil channel and are arranged circumferentially so as to face gaps between the coils and such that cooling oil receiving surfaces face upstream in a direction of flow of the cooling oil so as to change the cooling oil that flows through the cooling oil channel to an axial flow so as to be supplied to the gaps between the coils.
