发明名称 Rotary electric machine with increased cooling capacity
摘要 A rotary electric machine that controls fluid pressure and loss of cooling air, increases the cooling air flow rate, and is able to favorably cool the end of a coil with little regard to the positional relationship between the centrifugal blades and the end of the stator coil, is disclosed. A cooling fan of such a rotary electric machine includes centrifugal blades having deflecting blades disposed therebetween, which are mounted so as to incline towards an inside of the axial direction. The centrifugal blades and the deflecting blades are integrally formed. For this reason, the cooling air accelerates at areas between the individual blades in the centrifugal direction and is separated into two flows, one in the direction of inside portions and one in the direction of outside portions of the end of a stator coil. The end of the stator coil is cooled favorably. Thus, the eddy produced at the inside portions in the end of the stator coil is suppressed from flowing to the outside portions, and increases in fluid pressure loss are prevented.
