Claims

[Claims for Utility Model Registration] 1) An external fan-shaped rotating electrical machine, which has a centrifugal external fan fixed to the end of a rotating shaft protruding from the end face of the electrical machine body, and an external fan cover that surrounds the external fan. , a plurality of air intake ports are provided on the outer periphery of the outer fan cover at intermediate positions in the axial direction between the outer fan and the electric machine body, and a circular plate that guides outside air sucked in by the action of the outer fan from the air intake ports to the center of the outer fan. A shaped air guide and a plurality of cylindrical air guides that pass through the outer circumference of the air guide and guide cooling air produced by the action of the outer fan in the axial direction toward the outer circumference of the main body are arranged on the inner circumference of the outer fan cover. An external fan-shaped rotating electrical machine characterized by the following: 2) In the outer fan-shaped rotating electric machine as described in claim 1 of the utility model registration claim, the ends of the rotating shaft are made to protrude from both end faces of the electric machine body, and the outer fan is fixed to each end,
An outer fan-shaped rotating electric machine characterized in that the intake ports and cylindrical air guides of two outer fan covers surrounding the outer fan are provided so as to be alternately shifted in the circumferential direction.
