Abstract

PURPOSE:To eliminate the generation of the hottest point in a junction of stator winding by providing an outlet hole in a part of a ventilating tube as diverging a part of a cooling medium from a ventilating tube which passes the cooling medium. CONSTITUTION:Ventilating tubes 6a and 6b are constituted with several stages of accumulation. A hole 13 is made at the lowest ventilating tube closest to a junction 9. A stopcock 14 is mounted to a ventilating tube end. A cooling medium flows through space 15 around the junction 9 as 11a in the ventilating tube. Heat generated at the junction 9 is absorbed and dispersed as 12a and 12b. Said structure eliminates the generation of the hottest point at the junction 9.
