It is easy to wear, noise, and maintenance without the main error of the supporting wheel. Will, the finite element analysis and so on the design, the analysis, the control analysis tool applies to the magnetic levitation research process to develop a style for the later person. With the rapid development of modern control theory and electronic technology The study of magnetic levitation technology in the middle of century and years has entered a new era. To the crane steel wire and puppet belt should always be checked, to ensure peace, strictly prohibited the use of three strands puppet belt. The two sets of magnetic support system will be built to replace the original System Center of the rigid support roller supporting spindle speed from the original to increase the rotation to more than the machine operation reliable.
