초록

An airflow passageway structure for cooling open drip-proof rotating electric machinery utilizes a totally enclosed shaft bearing bracket spaced apart axially from a frame member, and an air inlet ring overlapping the gap between the frame member and the bearing bracket. Incoming cooling air moves axially along the air inlet ring, then moves radially inward between the bearing bracket and frame member. The cooling air then moves past an air deflector, a rotor or shaft mounted fan and finally exits from the machinery at ports located intermediate the ends...
