Modeling and analysis of a magnetically levitated synchronous permanent magnet planar motor with concentric structure winding

This paper propose a novel magnetically levitated synchronous permanent magnet planar motor with concentric structure windings. The analytical model of the novel magnetically levitated synchronous permanent magnet planar motor is established, flux density distribution of the two-dimensional Halbach magnet array is obtained by solving the equations of the scalar magnetic potential. Simulation results obtained by finite element method (FEM) is used to validate the analytical ones. A prototype motor is manufactured in laboratories and some experiments are carried out with the prototype.
