本研究提出一個可以同時達到高度調變致動與感測其高度變化能力之新式微型磁力模組。此磁力模組本質上近似於微尺度下之螺線管線圈,可調變微型陀螺儀中之懸浮轉盤,去除非柯氏力之因素所造成之傾斜與偏擺,使微型陀螺儀可正確量測外加之角激勵。當微型磁力高度調整器(Micro-Magnetic Height Adjuster, MMHA)之主線圈通入電流時,即可作為致動器調控懸浮轉盤。而二級線圈則作為感測器偵測懸浮轉盤與微型磁力高度調整器間之氣隙變化。
An innovative magnetic module which is concurrently capable of performing as an actuator and a sensor is proposed and illustrated. The magnetic module is basically similar to a micro-scale solenoid coil which is employed to actively adjust the height of a seismic rotating disc used in a gyroscope so that the induced pitch angle by Coriolis effect, purely due to exerted angular excitation, can be accurately measured. That is, the micro-magnetic module acts like an actuator for height regulation on the seismic rotating disc by applying appropriate electric current to the primary coil of the Micro-Magnetic Height Adjuster (MMHA). On the other hand, the secondary coil pair of the MMHA acts as a sensor which can detect the gap change between the seismic rotating disc doped by metal material, and the micro-magnetic module.
