摘　　要：研究了霍尔传感器的安装位置对混合斥力式磁悬浮系统性能的影响。通过建立电磁线圈有限元模型,分析了传感器在x、y、z三个方向的安装误差敏感性,确定了相应的误差容限。优化系统参数设计,将悬浮磁体直径从40 mm降至15 mm。实验结果表明,该系统实现的悬浮高度为22.7 mm,与原尺寸相近;位置波动平均误差小于0.2 mm,平均工作电流小于0.1 A。该研究为小型化磁悬浮系统的工程实现提供了理论依据。This study investigates the impact of Hall sensor installation position on the performance of hybrid repulsive magnetic levitation systems.By establishing a finite element model of electromagnetic coils,the sensitivity of sensor installation errors in the x,y,and z directions was analyzed,and corresponding error tolerances were determined.Through optimization of system parameters,the diameter of the levitation magnet was reduced from 40 mm to 15 mm.Experimental results demonstrate that the system achieved a levitation height of 22.7 mm,comparable to the original size,with an average position fluctuation error of less than 0.2 mm and an average working current of less than 0.1 A.This research provides a theoretical basis for the engineering implementation of miniaturized magnetic levitation systems.
