<P>PROBLEM TO BE SOLVED: To provide a rotary electric machine that provides effective cooling for a stator core and the like thereof. <P>SOLUTION: A rotary electric machine includes a rotor 20, a stator core 30, and a stator frame 40 that surrounds the stator core 30. The rotor 20 has: an annular member 21a that is annularly-shaped and rotatable; a plurality of mounts 22 that are fixed to an outer circumferential surface of the annular member 21a; permanent magnets 23 that are fixed to the respective mounts 22; and ventilation passage boards that have surfaces facing outer circumferential sides of circumferential gaps, that cover the circumferential gaps from a radially outer side, while straddling between circumferentially adjacent pairs of the mounts 22, so as to form rotor ventilation passages 70 penetrating through axial direction, and that have ventilation through-holes 71 formed on downstream sides thereof. <P>COPYRIGHT: (C)2013,JPO&INPIT |
