摘　　要：为了提高磁场调制式永磁齿轮(Field Modulated Permanent Magnetic Gears,FMPMG)的气隙磁密及传动转矩,基于某一具体结构的FMPMG,应用Ansoft14对其Halbach及平行充磁方式进行了分析比较,研究了永磁体厚度、转角差、轭铁厚度对气隙磁密及传动转矩的影响,结果表明:Halbach所形成的气隙磁密较平行充磁更具有正弦性;与平行充磁相比,Halbach气隙磁密的厚度极值点明显高于平行充磁;另外,Halbach特有的单边效应,使其对轭铁厚度的要求不高,可减小或取消轭铁结构以降低FMPMG的转动惯量,为大功率高性能的FMPMG实用化奠定基础。In order to improve the air-gap density and output torque of Field Modulated Permanent Magnetic Gears（FMPMG）, the magnets of parallel magnetization and Halbach array in a FMPMG was analyzed using ANSOFT14, and the magnet thickness, angle deviation and yoke iron thickness was studied about the air-gap density and output torque impact. The results could illustrate that the air-gap density, which was formed by Halbach array, was closer to sinusoid and has a higher amplitude than parallel magnetization. As a good self-shielding magnetization of Halbach array, the thickness of yoke iron could be decreased or removed to reduce moment of inertia of FMPMG, which would provide reference for further study and design about high-power and highperformance FMPMG.
