機。 A radial ventilation duct is provided in the stator core and the rotor core, and an axial ventilation path is provided in the inner circumference of the rotor core to communicate with the ventilation duct.
Internal ventilation type rotation in which the cooling air sucked from both ends of the ventilation path of the rotor core by the fan action of the ventilation duct and inner fan of the rotor core as it rotates is discharged through the ducts along with the cooling air passing through the outer periphery of the stator core. In an electric machine, a part of the space between a stator core and a cylindrical frame surrounding it is partitioned by an axial partition plate, and a part of the cooling air taken in from one end of the main body of the electric machine is channeled between the partition plate and the frame. An internally ventilated rotating electrical machine characterized by having an air passage that sends air from the outside of the inner fan to the other end of the air passage of the rotor core.
