Abstract

PURPOSE:To insure the necessary quantity of air and to elevate the cooling effect of the electric rotary machine without increasing the breadth of rim ducts or the number of stages of rim duct by a method wherein chamfers to reduce draft resistance are provided at the inlet part or at the outlet part of ducts for draft being provided in the rotor rim. CONSTITUTION:The spider 2 is joined to the shaft 1, and further the salient-poles 4 are equipped placing the rotor rim 3 between them. Plural rim ducts 31 for draft are provided in the rotor rim 3, and the chamfers 33 are provided at the end parts of manifolds 32 at the outlet parts of the rim ducts 31. The chambers 34 are provided at the inlet parts of the rim ducts 31. By this way, because the draft resistance is reduced, so that the sufficient cooling effect can be obtained only by the self fan action of the rotor.
