摘要
阐述了磁力联轴器传动的基本原理,介绍了磁力联轴器的Halbach阵列磁体形成的磁场特点。利用ANSYS软件对24极式磁力联轴器的传动转矩进行数值计算,分析传统磁体排列和Halbach阵列两种排列方式在不同转角差、磁极数、永磁体厚度和轭铁厚度时所传递的转矩。结果表明,Halbach阵列所传递的转矩较传统排列有明显的提高,为磁力联轴器传动转矩的进一步研究和大功率、高性能的磁力泵设计提供依据。
The basic principle of magnetic coupling was described. Then the magnetic field characteristics of Halbach array were introduced. ANSYS software was used to calculate the drive torque of the 24-pole magnetic coupling. The dependence of torque of magnetic couplings with both traditional and Halbach array magnets on angle deviation, numbers of magnetic poles, thickness of permanent magnets and yoke irons has been studied respectively. Compared with the coupling with traditional magnet arrangement, the coupling with Halbach array has a significantly improved torque. The results can provide reference for further study of the torque of magnetic coupling and the design of high-power, high-performance magnetic pumps.
