Claims

[Scope of Claim for Utility Model Registration] (1) A fully-enclosed externally ventilated rotating electric machine in which cooling air taken in from the load side of the rotating electric machine body is discharged to the opposite load side through a ventilation passage provided inside a cooling air guide cover. A rotating electrical machine characterized in that the vicinity of the outer periphery of the bearing housing portion of the load-side bracket is connected to the outside air, and a cooling fan motor for cooling the rotating electrical machine main body and the load-side bracket is provided on the load side. (2) The rotating electric machine according to claim 1, wherein the cooling fan motor is fixedly attached to the load-side bracket via a fan motor mounting plate. (3) The rotating electrical machine according to claim 1 of the utility model registration, characterized in that the opposite end of the cooling air guide cover is bent inward.
