摘要

本研究旨在将同轴磁齿轮应用于汽车动力传动系统中，以实现高效率的小体积转矩传递。本研究对含孤立铁颗粒的无取向电工钢（M400-50A）、钴合金钢（Vacodur 50）和软磁复合材料（Somoloy 700HR 5P）的磁性能进行了详细的研究。对高速侧为6000转/分，低速侧为1800转/分，传动比为3.33:1的同轴磁齿轮，进行了材料在低、高频时的磁性比较。采用Ansys Maxwell 2D有限元软件对相同尺寸的磁力齿轮进行了功率损耗、体积转矩密度和效率分析。数值分析表明，与其他材料相比，Vacodur 50具有优越的性能。结果表明，在不改变磁体体积的情况下，磁性齿轮的尺寸比M400-50A提高了约2.67%，比Somoloy 700HR 5P提高了约4.17%，同时保持了相同的效率值。总之，使用Vacodur 50在磁性齿轮允许更紧凑的设计在车辆动力总成系统比其他材料。

Reduction of core size and power losses of a soft composite magnetic gear

This study aims to achieve low-volume torque transmission with high efficiency by using a coaxial magnetic gear in vehicle powertrain systems. In this study, the magnetic properties of non-oriented electrical steel (M400–50A), cobalt alloy steel (Vacodur 50), and soft magnetic composite (Somoloy 700HR 5P) materials containing isolated iron particles are examined in detail. For the coaxial magnetic gear with a high-speed side of 6000 rpm, a low-speed side of 1800 rpm, and a 3.33:1 gear ratio, a magnetic comparison of the materials at low and high frequencies is presented. Power losses, volumetric torque density, and efficiency analyses for magnetic gears of the same size were performed using Ansys Maxwell 2D finite element software. The numerical analyses revealed that the Vacodur 50 provided superior performance compared to the other materials. It was found that without changing the magnet volume, the magnetic gear dimensions could be improved by approximately 2.67 % compared to M400–50A and by approximately 4.17 % compared to Somoloy 700HR 5P, while maintaining the same efficiency values. In conclusion, the use of Vacodur 50 in magnetic gears allows for more compact designs in vehicle powertrain systems than other materials.
