In order to minimize the detent force of permanent magnet linear synchronous motor (PMLSM) caused by end effect, a novel auxiliary poles one-piece structure is proposed. Two auxiliary poles are extended directly from two ends of the armature core. And magnetic isolation bridges are set between auxiliary pole and armature core. Compared with the conventional discrete auxiliary poles, the one-piece structure will reduce the manufacture difficulty of PMLSM with auxiliary poles and improve the reliability of linear motor.
