MANUFACTURE OF ROTARY ELECTRIC MACHINE
Document Type and Number:
Japanese Patent JPS59106863
Kind Code:
A
Abstract:
PURPOSE:To enhance the insulating reliability by facilitating the exfoliation of a protecting insulating layer for covering a non resin-impregnated ground insulating layer outside a coil conductor, thereby suppressing the thermal stress to be at an insulated coil to a low value. CONSTITUTION:An aromatic polyimide film is wound on the outer periphery of a coil conductor 1 to form a ground insulating layer 2. Further, aromatic polyamide paper and aromatic polyamide non-woven fabric are heat-press-bonded with silicone resin as a binder under the pressure of 5kg/cm<2> in an insulating tape, which is wound on the outer periphery to form a protecting insulating layer 3, and a non-resin-impregnated insulated coil 4 is manufactured. Two layers of the coil 4 are formed, the aromatic polyamide paper is enclosed as a slot liner 5, contained in the slot 7 of a core 6, a wedge 8 is hitted to the hole of the slot 7, heat resistant epoxy resin is fully impregnated, and thermoset.
