An optimal configuration of the flux-reversal linear synchronous motor (FRLSM) with the optimal number of attachment permanent magnets (PMs) was presented. The optimal model of 2 000 N was designed to reduce the detent force by redesigning the air-gap structure and skewing. The design parameters, mover PMs and stator core, were selected for optimal design by DOE. The thrust and the detent force of the designed optimal models were compared by finite element analysis (FEA). As a result, the thrust of the optimal model is slightly decreased by 1.97% compared with the basic model, and the detent force of the optimal model is greatly decreased by 88.47% compared with the basic model.
