摘要
为满足捷联惯性导航系统用动力调谐陀螺仪大跟踪速率的要求,提出了一种新的力矩器永磁磁钢结构。新结构参考Halbach永磁体阵列,在常规的双径向充磁磁环中间增加了一个轴向充磁磁环。利用电磁场仿真软件Maxwell对典型结构和新结构力矩器的工作气隙磁场进行分析,分析结果表明,新结构力矩器的力矩系数可提高36%。陀螺仪样机的实测结果验证了分析的结果。
A new structure of the permanent magnet for torquer is put forward to satisfy the requirement of high processing rate of the DTG for the strap-down inertial navigation. Refer to the Halbach magnet array, an axial-magnetized magnetic ring is mounded between the two radial-magnetized magnetic rings in the new torquer. The magnetic field in the air gap of the typical torquer and the new torquer is analyzed using the FEA software Maxwell. According to the analysis, the scale factor of the new torquer can increase 36%. The result of the analysis is verified by the test of the DTG.
