A Theoretical Investigation for Improving Dynamic Characteristics of Inductive position sensor

유도형 변위 센서의 동적 특성 향상을 위한 이론적 고찰

In a high speed spindle system, it is very important to monitor the state of rotating rotor. Particularly in active control spindle system, the position sensor must provide feedback to the control system on the exact position of the rotor. In order to monitor the state of a high speed spindle exactly, high accuracy and wide frequency bandwidth of sensors are important. This paper observes the factors which has an effect on dynamic performances of inductive position sensor.
