Abstract

PURPOSE:To enable effective cooling of a bearing by setting the ratio of the area of the hole of a suction port of an air guide to the area of the hole of an exhaust port of an outer fan cover at a special range, thereby effectively guiding the cooling air at the outside face opposite to the body of a rotary electric machine. CONSTITUTION:An outer fan cover 9 which covers an outer fan 8 and an annular air guide 11 which guides the cooling air of the fan 8 exhausted from the exhaust port 10 of the cover 9, sucked from a suction port 12 ans guided to the outside face are mounted on both outer peripheries of the body of a rotary electric machine. The area of the hole of the port 12 of the air guide 11 of the machine is set 1.7 to 2.3 times of the area of the port 10 of the cover 9. In this manner, the cooling air of the fan 8 is effectively sucked from the port 12 of the air guide 11 without scattering, thereby efficiently cooling the bearing 4 and the stator coil 2b.
