Characteristics Evaluation of Inductive Position Sensor for the State monitoring of a High Speed Spindle

고속 주축 상태 모니터링용 유도형 변위 센서의 특성 평가

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 describes the factors which has an effect on performances of inductive position sensor. We also report the experimental results that characterize the performances of the inductive position sensor.
