Claims

[Scope of utility model registration request]

(1) In a drip-proof protected rotating electrical machine that has internal air exhaust ports in the stator frame that supports the stator core of the rotating electrical machine, the stator core supporting ribs are formed to widen from the surface of the stator frame toward the inside of the machine. a hypotenuse, and an inside air exhaust port bored along the longitudinal direction of both sides of the stator frame surface of the stator core supporting rib;
A protrusion formed on the machine side of the stator frame near the inside air outlet so as to protrude from the stator frame toward the oblique side, a protrusion oblique side that expands and slopes from the base of the protrusion toward the outside of the machine, and a plurality of eaves. The drip-proof protection is characterized in that the angle of the oblique side and the oblique side of the protrusion and the mounting angle of the eaves are each inclined at an angle θ with respect to the horizontal, and the armor is attached to the outside of the machine at the inside air outlet. San-shaped rotating electric machine.

(2) A drip-proof protected rotating electric machine according to claim 1, in which the angle θ is 15° or more with respect to the horizontal.
