A Novel Approach of Thrust Ripple Minimization by Combinational Iron-cored Primary in Permanent Magnet Linear Synchronous Motor

摘要：

　　The paper presents a technique of combinational iron-cored primary for thrust ripple-free permanent magnet linear synchronous motor (PMLSM).Due to multiple end sides of primary iron-cores constructed, the low order harmonics of thrust ripple could be directly eliminated.At the same time, each phase of armature windings forms a circulating sequence at side edge, which enables the parameters of the armature windings to be symmetric and constant.Therefore, electromagnetic ripple caused by side effect will be directly removed.The theoretical analysis conducted reveals the basic characteristics of the proposed approach.Numeric simulation of the finite-element method and harmonic analysis verify the correctness of theoretic analysis and direct effects of the approach on eliminating thrust ripple.
