摘　　要：针对传统比例电磁铁的隔磁环结构加工工艺复杂、加工成本较高的问题,通过磁路分析,建立了一种齿形结构电磁作动器的数学模型,分析了其吸力特性的影响因素,从理论上揭示了齿形结构电磁作动器用作比例电磁铁的可能性。在此基础上,设计了一种不需要隔磁环结构的新型比例电磁铁,并利用试验验证过的有限元模型进行仿真分析,结果表明,所设计的新型比例电磁铁在大位移范围内具有优良的水平吸力特性。The existing proportional electromagnet is complex in process and high in cost because of the structure of magnetic isolating ring. To solve these problems, a mathematical model of electromagnetic actuator with tooth structure was established by analyzing magnetic circuit, the influence factors of attraction force characteristic were analyzed and the possibility of using electromagnetic actuator with tooth structure as proportional electromagnet was revealed theoretically. Thereafter, a novel proportional electromagnet was designed. The simulation analysis was performed with the finite element model validated by experimental results and the simulation results showed that the novel proportional electromagnet has excellent horizontal attraction characteristic within large stroke.
