Permanent magnet linear synchronous motor (PMLSM) is a new type of motor with high positioning accuracy. This paper introduces the related design theory of PMLSM with the utilization of finite element software. we refer to the sample transient electromagnetic analysis, firstly. And then get the Thrust fluctuation map and compare to its winding back EMF curve and other related graphs. Through altering of the thickness, air gap length, junior core’s structure and size and other parameters, we finally conclude the designed requirements will be eventually fulfilled this optimization.

Transverse Flux

This paper presents means to minimize the cogging force of a new type of permanent magnet excited transverse flux linear synchronous motor (PMTFLSM). The translator of this linear motor consists of cross-shaped core sets. Varying the parameters of air gap length, magnet dimensions, pole pitch and tooth width of the translator, the cogging force of the PMTFLSM will be analyzed. Taguchi's parameter method including 2D finite element analysis (FEM) is employed to minimize the cogging force. Analytical and simulation results indicate the usefulness of our approach in practice

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.
