Abstract

PURPOSE:To prevent leakage of cooling air flow and raise cooling efficiency and make the machine compact, by a method wherein a draft guide of cut-head conical wall shape is directed to a radial fan so that the gap between the radial fan and the inner wall of a casing is closed. CONSTITUTION:In a rotary electric machine where a radial fan 15 is installed at the shaft end and a draft gap is constituted between the inner wall of a casing 1 and the outer circumference of a stator 4, a wall 33 is provided so as to close the gap between the outer circumference of the radial fan 15 and the end of the casing. The wall 33 is of cut-head conical shape directed towards the radial fan 15, the diameter of the inner circumferential edge is equal to the outer circumferential diameter of the radial fan or less and the outer circumferential edge is fixed to a rim 32 of a draft guide. In this constitution, cooling air flows as shown in dashed line and does not leak thereby cooling effect is improved.
