Counter-flow cooling type electric rotary machine

Abstract

Abstract PURPOSE:To intensify cooling of the inside diametrical part of a magnetic flux shunt and to enable to magnify capacity of a counter-flow cooling elecric rotary machine by a method wherein a ventilation limiting ring is provided in a ventilating path adjoining to the magnetic flux shunt provided at the end part of stator as to feed a cooling wind to the inside diametrical side of the magnetic flux shunt. CONSTITUTION:At the stator being provided with the magnetic flux shunt 8 on the axial directional end face of a stator core 5 to shunt leakage magnetic flux, the limiting ring 13 to intercept ventilation is provided on the output port side of a ventilating path adjoining to the magnetic flux shunt 8 to make cooling gas G2C to flow along the inside diametrical part 8a of the magnetic flux shunt 8. Accordingly heating of the magnetic flux shunt 8 can be prevented, and capacity of the machine can be magnified.
