却構造。 Outside air is sucked into the machine by an internal cooling fan installed on the end face of the rotor, and this cooling air is divided into two, with some of the cooling air passing through the ends of the stator windings and cooling them through the ventilation holes in the core end plates. The other part of the cooling air cools the rotor, passes through the ventilation grooves of the stator core, cools the stator core and the straight part of the stator winding, and then is fixed. What is claimed is: 1. A ventilation cooling structure for a rotating electrical machine that discharges air to the rear side of a child core, characterized in that a mixed flow fan with a variable tilt angle is used as the internal cooling fan.
