A ROTOR FOR A ROTARY ELECTRIC MACHINE ABSTRACT OF THE DISCLOSURE A rotor structure draws surrounding air into chambers formed by adjacent pairs of spider arms through air inlet holes in cover plates enclosing the spider arms, due to the fan action of the spider arms upon rotation of the rotor. The air in the chambers then flows into the stator after cooling an annual yoke and windings. During this period, the high temperature portion of the machine is cooled by this. According to the ventilation structure of the present invention, the air inlet holes in the cover plates are out of alignment with each other so that air currents passing through them do not collide with each other, thus reducing windage loss and increasing cooling efficiency.
