The hybrid excitation flux switching linear magnetic suspension motor (HEFSLMSM) used in the traction system of the maglev train is studied. The permanent magnets, excitation windings and armature windings of the motor are all located on the primary short rotor, while the secondary long stator is only composed of magnetic core, which is suitable for the application of the long stator maglev train. Moreover, the motor has a simple structure, low price, sturdiness and durability, which can greatly reduce the system cost. The magnetic levitation operation principle of HEFSLMSM is studied. By establishing the flux and voltage equations of HEFSLMSM, the mathematical models of magnetic levitation force and electromagnetic thrust are deduced. The static characteristics and electromagnetic force of the motor are analyzed by finite element method, and the results show the feasibility of the magnetic suspension operation of the motor.
