機。 A radial ventilation duct is provided in each of the stator core and the rotor core, and an axial ventilation passage communicating with the ventilation duct is provided in the inner circumference of the rotor core to allow air taken in from one end of the electric machine body to flow through the rotor core. In an internally ventilated rotating electrical machine in which suction is carried out by a centrifugal fan through a ventilation duct, etc. and discharged from the other end, ventilation holes are provided in the small diameter portion of the other end of the main body and in the main plate of the fan, each substantially facing the ventilation path in the axial direction. 1. An internally ventilated rotating electric machine, characterized in that the main plate is provided with a ventilation hole and a ventilation path are communicated with each other through a cylindrical air guide concentric with the shaft.
