ELECTRIC MOTOR INSULATING SHEET AND A MANUFACTURING METHOD THEREFOR

WIPO Patent Application WO/2010/150669

A1

Provided is an electric motor insulating sheet forming a slot insulating sheet (12), in which aramid paper and a PPS film are directly pressure laminated without the use of an adhesive. Thus, an adhesive layer is not present between the aramid paper and the PPS film. The PPS film is low-cost in comparison to a polyimide film, has high thermal properties such as heat dissipation, and has a high resistance against heat. As a result, a high strength is maintained even when exposed to a high temperature for a long period of time. Additionally, since the aramid paper and PPS film are directly laminated without the presence of an adhesive layer, the overall thickness is reduced by a thickness equivalent to that of the adhesive layer, thereby enabling a thinner film.
