COOLING SYSTEM OF ELECTRIC MACHINE Russian patent published in 2004 - IPC

Abstract RU 2231195 C1

FIELD: electrical engineering, manufacture of electric machines.

SUBSTANCE: cooling system of electric machine has stator 1 with winding cooled by insulation fluid and separated from rotor 2 by insulation cylinder 3 with cooling tubes built into its internal surface. Rotor is cooled by air which is cooled by cooling tubes 7 is sequence. Tubes are built into cylinder and water coolers 6 are located in stator. Water circulates through cooling tubes 7 in opposition by supply of water into tubes from different sides of cylinder in turn.

EFFECT: enhanced operational reliability of electric machine, increased effectiveness of its cooling.
