Abstract
A rotary electric machine is installed such that a central axis of a rotating shaft is horizontal, and coolant suction apertures are formed at positions on a cylindrical portion of a frame that are vertically above first and second coil ends, and strip-shaped insulating papers are inserted such that a thickness direction is in a radial direction between radially adjacent conductor portions of portions of the conductor wire that constitute the first and second coil ends, and are disposed so as to extend circumferentially across positions that are vertically below the coolant suction apertures inside the first and second coil ends.
