Research is to further increase the display size of the original 3D display system to achieve a better display effect. In order to achieve our goal, we adopted a new method to achieve large-area rotation display and at the same time reduce the noise generated by rotating parts during high-speed rotation. In this study, the relevant technology of magnetic levitation bearing is used for reference[1] and the magnetic bearing is mainly used to offset the gravity of the intermediate turntable and reduce the noise generated by friction and the brushless motor is used to improve the speed of the turntable, hoping to obtain better imaging effect. At the same time, high-precision sensors are used to read the rotation speed and rotation Angle of the magnetic levitation bearing.
