Abstract

PURPOSE:To improve the cooling effect of a stator by forming a large number of unevenness to the inner surface of a ventilating hole for cooling and increasing the surface area of the inner surface of the ventilating hole. CONSTITUTION:A plurality of the ventilating holes 11B are shaped to the stator 1 while a large number of projections are formed to the inner surfaces of each hole. Accordingly, the cooling effect is improved because the surfaces areas of the inner surfaces of the ventilating holes 11B are increased more than the sectional areas of the ventilating holes 11B.
