Abstract

SUMMARY In this paper, a novel design for a tubular linear reluctance motor (TLRM) has been developed. This paper presents a novel structure to enhance magnetic force and velocity in TLRM. The new structure is accomplished through some changes in TLRM, which result in a step winding structure. For dynamic modeling of the proposed TLRM and obtaining the motor output characteristics, it is necessary that the inductance profile is calculated with a good accuracy. This paper represents a study of step winding inductance in every plunger positions in TLRMs with open-type magnetic circuits. Electromagnetic finite element analysis is used for proposed motor simulation and coil inductance calculation. Moreover, inductance of a prototype novel TLRM was measured with experimental methods. Simulation results of coil inductance calculation using three-dimensional finite element method with coil current excitation are compared with theoretical and experimental results. The comparison yields a good agreement. Copyright © 2011 John Wiley & Sons, Ltd.

用三维有限元法计算管状直线磁阻电机阶跃绕组结构的电感轮廓

本文提出了一种新型的管状线性磁阻电机(TLRM)。本文提出了一种提高TLRM磁力和速度的新结构。新结构是通过对TLRM进行一些改变来实现的，从而形成阶梯缠绕结构。为了对所提出的TLRM进行动态建模并获得电机的输出特性，需要高精度地计算电感曲线。本文研究了开式磁路tlrm中各柱塞位置的阶跃绕组电感。电磁有限元分析用于电机仿真和线圈电感计算。此外，用实验方法测量了新型TLRM原型的电感。用三维有限元法计算线圈电流激励下线圈电感的仿真结果与理论和实验结果进行了比较。比较结果很一致。版权所有©2011 John Wiley & Sons, Ltd
