METHOD FOR ELECTRICAL MACHINE WINDING INSULATION Russian patent published in 1997 - IPC

Abstract RU 2072115 C1

FIELD: electrical engineering. SUBSTANCE: prior to placing stator and rotor windings in respective slots, the latter are covered with laminate having elastically compressed mass of very flexible insulating fibers and thermosetting resin capable of softening at high temperatures though it is cured. After laminate is heated, it expands and fills the gap. EFFECT: facilitated filling of air gaps in slots. 14 cl, 5 dwg
