基于磁源重构的本安型电磁铁动态性能优化设计
Research on dynamic characteristics of intrinsically safe water-based solenoid pilot valve
摘要
Abstract
With the intrinsically safe electromagnets as the research object,this paper aims at the problems of intrinsically safe electromagnets due to limited power and inherent characteristics of magnetic materials,such as poor force-displacement characteristics,large inductance,and insufficient driving force,so as to improve the dynamic performance of electromagnet opening and closing response.Based on the method of magnetic reconstruction,a permanent magnet intrinsically safe electromagnet was proposed,which increases the electromagnetic force and force growth rate by introducing radial magnetized permanent magnet structure,and the equivalent magnetic circuit model of the electromagnet was used to explain the greater electromagnetic force and force growth rate.By using the Ansys Maxwell,the static and dynamic performance of the electromagnet was compared and analyzed,and the influence law of permanent magnet size on electromagnets'response time was discussed,which shows the dynamic performance of electromagnet is the best when the thickness of permanent magnet ring is about 6 mm.Results show that compared with the non-permanent magnet,the electromagnetic force of permanent magnet intrinsically safe electromagnet increases by 6.9％and the dynamic response time decreases by 9.3％,which has a great optimization effect,the simple structure,and is esay to be controlled and has the value of industrial promotion.关键词
