Title:
電動機用絶縁シートおよびその製造方法
Document Type and Number:
Japanese Patent JP5603029
Kind Code:
B2
Abstract:
An insulation sheet for electric machine that forms slot insulation sheet is configured by an aramid paper and a PPS film directly pressure laminated without use of an adhesive. This means that no adhesive layer interposes the aramid paper and PPS film. PPS film is less costly as compared to a polyimide film and possesses better thermal properties such as higher heat emissivity and is highly resistant to heat. Thus, high strength is maintained even when subjected to high temperature over extensive time. Further, because the aramid paper and PPS film are laminated directly without an adhesive layer, the laminate is reduced in thickness. This allows further thinning of the laminate.
