Novel Design

This paper presents an analysis of a new type of permanent magnet excited transverse flux linear synchronous motor (PMTFLSM). This linear motor achieves a high thrust from its novel design and fabric. Its translator consists of cross-shaped core sets. Considering parameters such as magnet dimension, pole pitch, and tooth width of the translator, the effected thrust is analyzed and simulated with a 2D model of our PMTFLSM using the finite element method. Extensive simulations were conducted to investigate how the motor performs under a variety of parameter settings. Accordingly, motor characteristics are identified whereby an optimal combination of parameter values can be found. The new findings are then fed back to our motor design to validate performance improvement.

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

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.

In this paper the research results for reducing the detent force in one innovative permanent magnet linear synchronous motor for 2D laser marking system was published. There two methods are used. The first of these methods features the usage of two additional end teeth with chamfers in the magnetic circuit of the movable part. In the second method, the teeth of the ferromagnetic core are with different lengths. As a result of the change of the air gap permeance in both cases substantial reduction of detent force is achieved, in multiples at times. The results obtained are based on modeling and analyzing the linear motor magnetic field by the Finite Element Method (FEM). Provided experimental research of the linear motor prototype proves the correctness of the simulations results.

Basic Characteristics

The paper presents a technique of combinational iron-cored primary for thrust ripple-free permanent magnet linear synchronous motor (PMLSM). Due to multiple end sides of primary iron-cores constructed, the low order harmonics of thrust ripple could be directly eliminated. At the same time, each phase of armature windings forms a circulating sequence at side edge, which enables the parameters of the armature windings to be symmetric and constant. Therefore, electromagnetic ripple caused by side effect will be directly removed. The theoretical analysis conducted reveals the basic characteristics of the proposed approach. Numeric simulation of the finite-element method and harmonic analysis verify the correctness of theoretic analysis and direct effects of the approach on eliminating thrust ripple.
