A water-cooled, double-sided permanent magnet linear synchronous motor (PMLSM) is studied by electromagnetic and thermal finite-element (FE) analysis method. Based on electromagnetic analysis, the better structure of this double-sided PMLSM can be obtained after thrust optimization by adjusting motor structure parameters. In order to minimize the thrust ripple, it is further optimized by shifting permanent magnets or armature iron cores of two sides for a small distance. With thermal analysis, the temperature distribution and transient temperature variation of this optimal PMLSM are investigated under the continuous operation and the short-time operation.

The One

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.
