| Abstract: | In order to improve the Servo characteristics of permanent magnet linear synchronous motor （PMLSM） used in the feed system of modern top-end numerous con-trol machines, means to reduce the thrust fluctuation of the PMLSM were studied. After analyzing the fluctuation mechanism, it was found that the cogging ＆ edge effect and formal force were the main cause. |
