| Abstract: | The principle and characteristic of high thrust permanent magnet linear motors(HT-PMLSM)was introduced.The end effect and slot effect would result in cogging force was indicated.A novel electromagnetic structure scheme of segmented windings and iron cores with cyclic permutation order and shifted relative location among segments for HT-PMLSM primary part was presented.Counterpoise of the end effect and slot effect with the novel scheme was analyzed.The result showed that the novel scheme could effectively improve the smooothness of the thrust of HT-PMLSM. |
