发明名称 ROTARY ELECTRIC MACHINE
摘要 PROBLEM TO BE SOLVED: To provide a rotary electric machine which enables improvement of the reliability of feed brushes.SOLUTION: A rotor 5 is rotatably attached to a first body 2 and a second body 3 of an alternating-current generator 1. A pair of feed brushes 9a, 9b slidably contacts with slip rings 5e, 5f formed on a rotary shaft 5d of the rotor 5. An air-intake port 12 is formed between the second body 3 and a rear cover 11, and a flow regulation device 13 is disposed so as to face the air-intake port 12. The flow regulation device 13 includes a heat sink 14 to which power modules 15 are attached. The heat sink 14 includes: plural cooling fins 14b extending in a radial direction; and a shield wall 14c which extends on a circumference and connects inner end parts of the cooling fins 14b with each other. Cooling air entering from the air-intake port 12 passes through the heat sink 14 to cool the power modules 15. The cooling air is shielded by the shield wall 14c and is blocked from reaching the feed brushes 9a, 9b.
