示す。Figure 1 shows a conventional forward/reverse rotary external fan-shaped rotating electric machine. FIG. 2 is a side view showing an embodiment of the invention. In the figure, 1 is the frame, 1a is the four seats, 1
b to 1g are multiple heat dissipation fins, 1b' to 1h' are multiple ventilation channels, 2 is the anti-load side bracket, 2a is the coupling ratio of 4, 4 is the rotating shaft, 5 is the external fan, and 6 is the external The fan cover 9 is an outer cover. Note that the same reference numerals in the figures indicate the same or corresponding parts.

Claims

[Scope of utility model registration request]

(1) An outer cover of a rotating electrical machine that rotates in forward and reverse directions and has a plurality of radiating fins in the axial direction formed on its outer peripheral surface, and an outer fan that is connected to a protrusion of a rotating shaft that protrudes from the outer end surface of one side of the outer cover. and an outer fan cover that surrounds the outer fan, which maximizes the heat radiation area of the heat radiation fins that maximizes the cooling effect of the cooling air from the outer fan when the outer fan rotates in the forward or reverse direction; A forward/reverse rotating external fan-shaped rotating electric machine characterized in that the heat radiation area of the heat radiation fins is formed to become smaller in order as the cooling effect becomes smaller.

(2) The forward/reverse rotating external fan-shaped rotating electric machine as claimed in claim 1, wherein the size of the heat radiation area of the plurality of radiation fins depends on the height of the plurality of radiation fins.

(3) The forward/reverse rotating external fan-shaped rotating electric machine as set forth in claim 1 of the utility model registration claim, wherein the radiation fins with the largest heat radiation area are radiation fins formed on both sides of each of the four seats. .
