<p>PROBLEM TO BE SOLVED: To obtain a dynamo-electric machine which allows for avoidance of decrease in productivity and deterioration of fan noise, while enhancing the cooling performance.SOLUTION: At the end of a rotor 2 in the axial direction, a cooling fan 5 is provided. The cooling fan 5 generates cooling air by rotating integrally with the rotor 2. A stator core 11, arranged at a position on the radial outside of the rotor 2, is provided with a plurality of stator coils 12 side by side in the circumferential direction. Each stator coil 12 has a coil end 12a protruding from the end face of the stator core 11 in the axial direction. A front side housing 13 covering the cooling fan 5 is provided with an exhaust port 26, at least a part of which existing at a position on the radial outside of the coil end 12a and passing the cooling air, and a recess 27 facing the coil end 12a in the axial direction.</p> |
