Optimization of the Structural Parameters of the Magnetic Coupling Transmission Gate Valves

摘要: 基于磁力耦合传动闸阀(Magnetic Coupling Transmission Gate Valves, MCTGV)运行机理建立其有限元模型，对MCTGV的电磁转矩特性进行分析。通过控制变量法对MCTGV永磁体极对数、隔离套厚度、永磁体厚度及气隙长度等参数与传递转矩的关系进行仿真分析，并对上述参数逐一优化。结果表明： MCTGV中的各结构参数对转矩影响较大，经优化后可较大提高其输出转矩。

Abstract: Based on Magnetic Coupling Transmission Gate (Magnetic Coupling Transmission Gate Valves, MCTGV) operation mechanism, this paper established the finite element model, and analyzed the electromagnetic torque characteristics of MCTGV. The relationship between these parameters of MCTGV including the logarithm of magnet, the thickness of permanent magnet, air gap length and the torque characteristics is analyzed in detail by using the control variable method, and the above parameters are optimized one by one. The results show that these structure parameters of MCTGV have a great influence on torque performance, and the output torque has been greatly improved by optimizing.
