    摘要： PROBLEM TO BE SOLVED: To provide an insulating sheet for a motor, along with its manufacturing method, in which both thermal characteristic and durability are attained at low cost for contributing miniaturization of a motor and improved performance.SOLUTION: In an insulating sheet for a motor which forms a slot insulating sheet 12, an aramid paper and PPS film are directly pressurized and laminated with no use of an adhesive. In other words, no adhesive layer is interposed between the aramid paper and the PPS film. The PPS film is cheaper than a polyimide film, and has a high thermal characteristic such as heat radiation property, with high resistance against heat as well. As a result, even if it is exposed to a high temperature for a long period of time, its high strength is maintained. Since the aramid paper and the PPS film are directly laminated with no intervention of adhesive layer, the thickness corresponding to the adhesive layer is reduced for thin film formation.

    摘要翻译： 要解决的问题：提供一种用于电动机的绝缘片及其制造方法，其中以低成本实现了热特性和耐久性，从而有助于电动机的小型化和改进的性能。解决方案：在用于 形成狭缝绝缘片12的电动机，芳族聚酰胺纸和PPS膜直接加压并层压而不使用粘合剂。 换句话说，在芳族聚酰胺纸和PPS膜之间没有粘合剂层。 PPS膜比聚酰亚胺膜便宜，并且具有高的热特性，例如散热性，耐热性也高。 结果，即使长时间暴露于高温下也能保持高强度。 由于芳族聚酰胺纸和PPS膜直接层压而没有粘合剂层的干涉，所以与薄膜形成相应的粘合剂层的厚度减小。
