Claims

[Claims for Utility Model Registration] 1. An outer frame of a rotating electric machine, an air intake cover installed on the outside of the outer frame, communicating with one end of the outer frame via an air exhaust cover, and with the other end of the outer frame. a cooling fan that is attached to one end of the rotating shaft of the rotating electrical machine and circulates the air within the outer frame from the air exhaust cover side through the cooler to the air intake cover side; , a partition plate that is attached to the air intake cover and forms a space that isolates the inside of the outer frame from the outside air together with an air stopper and communicates with the outside air through a minute gap together with the air intake cover;
A fully enclosed rotating electric machine comprising: a cooling air receiver that introduces a portion of the circulating air from the cooler into the space; and an intake ventilation pipe that introduces outside air into the outer frame through a filter. 2. The fully enclosed rotating electric machine according to claim 1, wherein the cooling air receiver is provided through the partition plate. 3. The fully enclosed rotating electric machine according to claim 1, wherein the cooling air receiver is installed between the inner surface of the air intake cover and the partition plate. 4. The intake ventilation pipe is a fully enclosed type according to any one of claims 1 to 3 of the utility model registration claim, wherein the intake ventilation pipe is provided through the air exhaust cover and is fixed to the flange part of the outer frame with a nut. Rotating electric machine. 5. The outer end of the suction ventilation pipe is communicated with an air supply port cover attached to the outer surface of the air discharge cover, and the air supply port cover is provided with a filter.
