Characteristics Analysis of Novel Transverse Flux Linear Synchronous Motor for Maglev Transportation

The magnetic levitation (Maglev) transportation mainly completes the propulsion, levitation, and guidance (PLG) functions, which generally require the application of linear motor. Based on this, a novel transverse flux linear synchronous motor (TFLSM) is proposed in this article, which is integrated with PLG. The whole structure and principle of the novel TFLSM are discussed. Then, the air-gap magnetic flux density is calculated based on the equivalent current layer analysis method, and the propulsion and levitation are calculated with different operating times. Besides, the guidance force is calculated with different transverse displacements by using the Schwarz–Christoffel (SC) conformal mapping method. After the simulated of the finite element model, the analytical results of the forces are compared with the finite element method (FEM). Finally, all the calculated results of the PLG are validated by an experimental prototype, which provide an electromagnetic theory analysis for electromagnetic suspension (EMS) transportation that integrated with PLG.
