Kind Code:
A
Abstract:
To ensure cooling efficiency of a totally-closed fan-cooled dynamo-electric machine with a simple structure.SOLUTION: A totally-closed fan-cooled dynamo-electric machine 300 comprises: a rotator 10; a stator 20; a frame 40; two bearings 30; two bearing brackets 45a and 45b; a cooling device 60 that cools air for cooling by external air; a cooling apparatus 200 including a movable separation mechanism 100 that separates the inside of the cooling device 60 into two flowing paths in an axial direction; inner fans 51a and 51b; an outer fan 55. The cooling device 60 comprises: a plurality of cooling pipes 61; and a cooling device cover 63 that is communicated by a space in the inside of the frame 40, cooling device inlet opens 64a and 64b, and a cooling device outlet open 65. The movable separation mechanism 100 includes: a separation plate 101 that is arranged in vertical and in the rotational axial direction in the inside of the cooling device 60 and is movably formed in a rotational axial direction; and a moving and driving part that moves and drives the separate plate 101.SELECTED DRAWING: Figure 1
