This paper presents a dynamic simulation model which fully describes transient and steady-state operation of flux reversal linear synchronous motor (FRLSM). Magnetic field computations by finite element analysis considering inter-phase coupling effect are performed to establish phase decoupled voltage equation for the dynamic simulation. Simulation parameters such as thrust, normal force, flux linkage, and core loss are obtained by magnetic field computation and put into look-up tables. The validity of the model is verified by experiments under various operating conditions.
