回転電機。 A stator core having a radial ventilation duct and a rotor core having a ventilation passage and a radial ventilation duct between the fitted rotor shaft are housed inside a frame, and the rotor shaft is attached. In a variable speed rotating electric machine equipped with a ventilation cooling mechanism that circulates through the ventilation passage and each ventilation duct using an internal fan, the cooling air passing between the rotor core and the rotor shaft may circulate through the ventilation duct. A partition plate provided between the rotor core and the rotor shaft is attached to the end face of the rib via a spring so as to reach the stator core via the rib, and the partition plate is in contact with the partition plate. A ventilation guide is provided in which a cam whose center of gravity changes with respect to the rotor shaft in response to changes in rotational speed is fixed, and the partition plate is movable in the axial direction according to the movement of the cam. Characteristic variable speed rotating electric machine.
