Abstract

PURPOSE: To perform a cooling of a stator iron core effectively by making a flow of a cooling wind within a revolving electrical machinery to go from a stator side to a rotor side.
CONSTITUTION: A cooling fan 9 absorbing a cooling wind from a center part vicinity of a rotor iron core 2 and exhausting to an exhaust duct 10 surrounding stator ends 5 at both outer sides of a stator iron core 3 is mounted on a shaft 1. A cooling wind of outside flows into a ventilating duct 7 of a rotor iron core 2 through a ventilating duct 8 of a stator iron core 3 towards to a center part vicinity of a rotor iron core 2. In this manner as a stator iron core 3 and a rotor iron core 2 can be cooled sufficiently, a dimension of a shaft 1 direction can be shortened.
