Abstract

PURPOSE: To reduce the inlet pressure loss of cooling wind and raise its cooling effect, by chamfering the edges of a stator iron core around the inlet ports of air ducts to increase the cross-sectional area of the inlet ports.
CONSTITUTION: The cooling wind is conducted from a rotor fan 1 to the air ducts 4 of a stator through a rotor 2. The edges of the stator core of stratified iron sheets around the inlet ports of the air ducts 4 provided in the inner part of a tooth block 3b of the stator core are chamfered, thereby increasing the cross-sectional area of the inlet ports of the air ducts 4. Thus, the inlet pressure loss of the cooling wind is greatly reduced and its cooling effect is raised.
