Abstract

PURPOSE: To decrease forced pressure necessary for required quantity of a cooling wind flow and the power of a fan while improving efficiency, by diminishing pressure loss wherein the inlet portions of the cooling wind of a rim of a rotor are rounded.
CONSTITUTION: End portions in the axial direction at the outer circumferential side of a rim 1 of a rotor - that is, upper and lower ends - are rounded 10. Thus, since the value of an inlet loss coefficient k of the inlet pressure loss Δp=(r/2g)k.v2 of a cooling wind in inlets between magnetic poles can be lessened to not more than value such as 0.25, the pressure loss of the inlets of the rotor is decreased, and efficiency is heightened while the dimensions of this machine can be compacted.
