TOTALLY ENCLOSED ELECTRIC ROTATING MACHINE

摘要

PROBLEM TO BE SOLVED: To improve heat dissipating property of an electric rotating machine by making temperature distribution of the outer surface of the rotating machine uniform. SOLUTION: A fine tube 3 as a heat transport tube is fixed to a frame 2 in a state that heat conduction is performed between the thin tube 3 and the frame 2 and heat transport is performed from a high temperature part to a low temperature part of the frame 2 through the thin tube 3.
