Speed control of double-sided linear flux-switching permanent magnet motor system for electromagnetic launch system

In this paper, a new double-sided linear flux-switching permanent magnet (DLFSPM) motor for electromagnetic launch system is proposed, in which the mover only consists of yokeless iron while the permanent magnets and armature windings are all located on the stator. Hence, this motor incorporates the merits of high thrust density of permanent magnet linear motor and high reliability of linear induction motor in high speed electromagnetic launch system. The mathematical model and field-oriented control strategy of DLFSPM is investigated. The simulation results indicate that the DLFSPM can offer a very good dynamic performance based on the selected control strategy.
