Abstract: In order to meet the needs of electronmechanical servo actuators, a novel conductive plastic potentiometer with high reliability and better wear resistance is proposed. During long period of services, some insulating grinding grits will precipitate from the resistance body due to repeatedly friction with brush. Which bring an inherent defect for the existing conductive plastic potentiometer. That is, the occasionally data mutation of servo system, which greatly impact data interpretation. Nevertheless, the improved conductive plastic potentiometer proposed in this paper has optimized it’s structure and material, successfully overcome the defect and greatly extend longevity of the potentiometer. Therefore, the increasingly high requirements of electronmechanical servo actuators about reliability, wear resistance, longevity to potentiometer are well satisfied.
