Abstract

PURPOSE:To realize miniaturization by axially forming ventilating duct in a rotary shaft part and at the same time, diamaterically forming ducts in a rotor iron core and a stator iron core and by providing partition around the external circumference of rotary rectification device. CONSTITUTION:A ventilating duct is axially formed by the spider groove 31 of a rotary shaft part. At the same time, ducts 511 and 611 are axially formed in the rotor 5 and the stator 6 respectively. In addition, an air passage 711 is axially formed in a rectifier wheel 71 of a rotary rectification device 7, and a partition 14 having an opening 141 as if to surround the circumference of a rotary rectification device 7 is provided. Then air cooled by an air cooler 15 is sucked into a spider groove 3 under the fan effect of a rotor 5. Part of the air is returned to the cooler 15 through ducts 511 and 611 and the remainder to the cooler 15 via air passages 711 and 141 under the fan effect of the rotary rectification device 7.
