Calibration data acquisition apparatus and calibration system

摘要

The present invention provides a motor that rotates a rotating shaft, a magnetic field generator that generates a magnetic field when rotating the rotating shaft to change a magnetic flux direction, a magnetic sensor that is fixed to the rotating shaft and measures voltage values corresponding to the magnetic flux direction, and an actual shell In order to calibrate the voltage values of the shell magnetic sensor built into the shell to calculate the posture of the shell, the voltage values measured by the magnetic sensor divided according to the rotation speed of the motor and the magnetic flux direction are stored as calibration data. It provides a calibration data acquisition device including a controller.
