Solving the problem of high-speed development of optical drive hard disk with magnetic suspension bearing

This paper mainly discusses the use of magnetic suspension bearings to replace the spindle bearings of optical drives and hard disks in general car audio-visual systems to overcome the difficulties faced by optical drives and hard disks in the development of high-speed. Based on practical considerations, a low-cost three-pole magnetic levitation system is designed to compete with existing systems for minimum energy loss and lower cost analysis.
