Abstract

PURPOSE:To raise the cooling effect of a rotary electric machine by providing a ventilating duct passing axially between the base ends of the poles of a salient- pole type rotor core and radially providing a ventilating duct communicating with the duct in a rotor core, thereby increasing the heat sink area. CONSTITUTION:Core members 3a-3c having, for example, 4-salient pole type poles 2 are arranged axially at an equal interval around a rotational shaft 1, opposing faces of the adjacent poles 2 axially at the members 3a-3c are coupled via planar spacers 4, and the second ventilating duct 8 which extends in a direction perpendicular to the shaft 1 is formed at each gap among the members 3a-3c. The first ventilating duct 5 faced via insulators 6 with the end faces of field coils 7 wound on the poles 2 at both sides in parallel with the shaft 1 is provided between the base ends of each pole 2 of the members 3a-3c.
