Harmonic Analysis of Magnetic Field Measurement of Maglev Plane Motor

With the rapid development of production scale and technology level in field precision engineering technology, plane motor is a new type which can directly output motion has characteristics simple structure, high fast response speed. In this paper, magnetic levitation (MLPM) as research object, it hot recent years, MLPM good application prospect driving advanced manufacturing equipment used under vacuum conditions. harmonic are analyzed by establishing analytical model each odd harmonic. The actual permanent magnet array measured on measuring platform Tesla meter, measurement results analyzed. And then data compared with data. Further calculation shows that maximum relative error between simulated decreases gradually increase order field.
