Open publisher page 2 citations

Abstract

The principle,structure and magnetization law of Halbach array are analyzed to increase the thrust force in a permanent magnet linear synchronous motor(PMLSM).The appropriate structure of Halbach array was designed for the PMLSM.The no-load thrust characteristics of the PMLSM were compared using different Halbach arrays.The analysis results show that the PMLSM with Halbach array can improve the air-gap magnetic flux distribution,enhance the thrust of motor and reduce the thrust ripples.Therefore,the PMLSM with Halbach array is prior to one with normal array.
