摘要

Centrifugal fans are fixed to axial end surfaces of first and second pole cores such that 0.2 < t/h < 0.7, where t is an amount of axial protrusion of the centrifugal fans relative to apex portions of front-end and rear-end coil end groups of a stator winding and h is an axial height of the centrifugal fans.
