Abstract

PURPOSE:To prevent cooling liquid from being infiltrated into a space between a stator and a rotor, by providing the upper section of a casing with cooling liquid injecting slots, and by arranging labyrinth sections at rotor end sections on the injecting slot side and drains under the labyrinth sections. CONSTITUTION:Cooling liquid injected from cooling liquid injecting slots 32, 34 flows downward close by the end surfaces 44, 46 of resin mold members 28. Most of the cooling liquid flows downward close by the respective released end surfaces 48, 50 of labyrinth members 18, 20, and flows out of outflow slots 36, 38 arranged at the lower ends of a casing 24. The partial cooling liquid is infiltrated into labyrinth sections composed of the labyrinth members 18, 20, and the labyrinth sections are composed so that the liquid may flow near the outflow slots 36, 38 out of drains 40, 42. The respective drains 40, 42 are arranged at the lower ends of the resin mold members 28 so that the drains may pass spaces in the circumferential directions of stator coils 26.
