PROBLEM TO BE SOLVED: To efficiently execute cooling of slip rings and brushes without increasing the size of a configuration of a rotary electric machine.SOLUTION: Each air-blowing blade 100 is erected on each bus bar 99u, 99v, and 99w for electrically connecting each slip ring 97u, 97v, and 97w with each rotor winding 30. Cooling air is generated by air-blowing blades 100 during rotation of an input shaft 34. The cooling air is blown against the slip rings 97 and brushes 98 to cool the slip rings 97u, 97v, and 97w and the brushes 98u, 98v, and 98w. |
