高分子PTC材料在微电机自保中的应用

The Polymer PTC Materials and a New Type of Micromotorwith SelfProtective Using Polymer PTC Materials

本文研究了高分子ＰＴＣ材料的性能，并利用高分子ＰＴＣ材料将传统的微电机改造成了具有自保结构的新型微电机。实测数据与理论设计吻合较好。

The properties of polymer PTC materials are studied. A traditional micromotor is reformed into a new type of micromotor with selfprotective structure using polymer PTC materials. The tested data coincide well with the theory data.
