Rotating electric machine, rail vehicle and electric vehicle equipped therewith

摘要

Object Not only inside air but also coil end part of a stator 2 are prevented from becoming high in temperature, and cooling performance is improved. Solution to Problem In order to achieve the object described above, a rotating electric machine 1 of the present invention is made up of a stator 2 and a rotor 3 oppositely arranged through the intervention of predetermined air gap at the inner diameter side of the stator 2; the stator 2 has a stator iron core 4, a plurality of stator slots 12 that extend in the axial direction and are formed in the circumferential direction at predetermined intervals at the inner diameter side of the stator iron core 4, and stator coils attached in the plurality of stator slots 12; the rotor 3 has a rotor iron core 7, a plurality of rotor slots 6 that extend in the axial direction and are formed in the circumferential direction at predetermined intervals at the outer circumference side of the rotor iron core 7, and magnetic field members inserted in the rotor slots 6; and the rotor iron core 7 has an outside air ventilation hole 17a for ventilating air outside the machine and an inside air ventilation hole 16 for ventilating air inside the machine.
