Application of inductive and capacitive sensors in magnetically suspended gyroscope

Effective detection of the rotor plays an important role in the magnetically suspended gyroscope,which is an emerging inertial navigation device.In this paper,the principles of inductive sensors and capacitive sensors were analyzed and differential detection sensors were designed,the transformations from non-electrical measurements to electrical measurements were calculated,and the sensors were applied to the detection of displacement and angular deflection of the rotor.Results showed that acceleration and angular velocity can be successfully measured by the sensors.
