Electric rotary machine with cooled conductors

摘要

In order to provide an electric rotary machine in which the cooling performance can be improved without providing specific means on the flow path and without increasing a flow rate of cooling gas, a plurality of through holes 21 perforated in each of plate-shaped conductors 16 forming a winding conductor 15 are arranged in plural rows of through holes 21a, 21b in the width direction of the plate-shaped conductor, a plurality of cooling gas flow paths 20 formed in the winding conductor 15 branch off into plural rows and a cooling area for the cooling gas is increased. <IMAGE>
