Abstract
PURPOSE: To raise the cooling performance of a rotary electric machine, by providing a cooling fin with an axial hole of the same diameter as that of a rotary shaft and coupling the cooling fin to the shaft.
CONSTITUTION: An axial hole 2 is provided in the central part of the rotary shaft 1 and extends to the cooling fin 11. The fin has an exial hole 12 of the same diameter as the former 2. The cooling fin 11 is fixed on the rotary shaft 1 so that the inside surfaces of the shaft and the fin coincide with each other. A heat pipe action is thus caused to raise the cooling performance of the rotary electric machine.
