The typical structure of single freedom degree liquid floated gyroscope is shown in the figure at right.
The main functions and characteristics of each component are described below.
Gyroscope motor : It provides gyroscope momentum moment,usually using 3-phase or2-phase hysteresis synchronous motor,or permanent magnet motor,etc.,usually in the form of internal stator external rotor.The bearing can be either ball bearing or dynamic air floating bearing.
Sensor components:Transfer the mechanical rotation angle of float component relative to shell to electrical signal,usually with a moving coil type and a micro synchronous device type angle sensor.
torquer component:Torquer is generated by using electromagnetic principle, permanent magnet torquer and electromagnetic torquer are common.
float component(gyro component):usually cylindrical,also spindle-shaped(gyroscope room),which is equipped with motor,pre-vacuum and filled with high-purity helium gas or hydrogen under certian "neutral force".The external part is filled with suspended liquid,with float balancing mechanism at both ends and a pivot axis.
