Title:
SALIENTTPOLE TYPE ROTARY MACHINE
Document Type and Number:
Japanese Patent JPS55144745
Kind Code:
A
Abstract:
PURPOSE:To improve cooling effect to a large capacity by a construction wherein a cooling air passage for rotor and stator is separated by providing a partition wall on inside diameter side of the stator, and a stator frame is partitioned more than one to provide cooling fans alternately. CONSTITUTION:A cylindrical partition wall 32 is formed on inside diameter side of a stator core 13 to provide a rotor side and a stator side. The partition wall 32 can be formed solidly with a slot wedge. Further, a partition wall is provided so as to seprate space formed between the stator core 13 and a stator frame 2 circumferentially or diameterally more than one, and the partitioned spaces are used alternately for stator frame inflow section 22 and stator frame outflow section 25 to mount a stator cooling motor fan 15 and a stator ventilating system air cooler 16 respectively therein. The stator and the rotor can now be cooled separately each other, therefore a cooling effect is improved to a large capacity.
