ROTOR OF LIQUID-COOLED SALIENT-POLE SYNCHRONOUS MACHINE Russian patent published in 1995 - IPC

FIELD: liquid-cooled electrical machines. SUBSTANCE: machine rotor has shaft 2 carrying salient-pole inductor core with field coils wound on poles. Indirect coolers are placed between layers and have highly heat-conducting mass with built-in corrosion-resistant nonmagnetic tubular members of forward and reverse hydraulic circuits connected to distribution chambers with pipe unions. EFFECT: 25-35% better space factor of interpole space filled with conducting material which raises machine efficiency due to reduced excitation loss; reduced maintenance charges for water treatment system due to using cleaned running water for cooling. 4 cl, 3 dwg
