摘　　要：提出一种基于铁基纳米晶合金的非接触式扭矩传感器。为了达到非接触和受转轴振动影响小的目的,采用多磁极、环形结构,利用铁基纳米晶合金的逆磁致伸缩效应来制作传感器。通过试验确定了传感器的各项参数,验证了转轴振动对输出的影响。试验结果表明,灵敏度为2.692 mV/V,非线性误差为0.13%,最大重复性误差为0.223%,迟滞误差为0.26%,精度为0.473%;转轴振动对传感器输出的影响不大。A kind of non-contact torque sensor based on Fe-based nanocrystalline alloy is researched in this paper.In order to achieve the purpose of non-contact and less affected by rotating shaft vibration,multi-pole and circular structure is adopted.The sensor is made based on the principle of inverse magnetostrictive effect of Fe-based nanocrystalline alloys.The sensor parameters are determined and the influence of shaft vibration on sensor output is verified by experimenting.The experiment shows that the sensitivity is 2.692 mV/V,non-linear error is 0.13%,maximum repeatability error is 0.223%,hysteresis error is 0.26%,and accuracy is 0.573%.Rotary shaft vibration has little effect on output.
