Propulsion, levitation, and guidance (PLG) are the main technologies of high-speed maglev system. A linear synchronous motor (LSM) integrated with PLG is presented, which can simultaneously realize the three functions of the maglev system by only one electromagnetic system. A novel bilateral Fourier decomposition method for analyzing the 3-D force characteristics of the LSM is proposed, which has the advantages of wider range of solutions, simpler formulation, shorter computation times, and satisfactory precision. First, the topological structure of the LSM is introduced, and the 3-D magnetic field generated by the secondary superconducting (SC) coil is calculated. Second, the primary current of the combined coil is decoupled into PLG current, and then, the analytical expressions of forces generated by three currents are obtained. Finally, the 3-D force characteristics of the LSM at different running speeds, different suspension heights, and lateral offset of the maglev are calculated, and the correctness of the theory is verified by the publicly measured data on the Yamanashi line. The results obtained by the bilateral Fourier decomposition method provide a certain reference value for the LSM integrated with PLG in the initial stage of electromagnetic design.
