Abstract

This paper presents some novel force ripple reducing techniques for tubular permanentmagnetlinear machines (TPMLMs) with the square-shaped cross section. These methods are verystraightforward, so their implementation in TPMLMs with the square cross section is easy. Ananalytical form of machine parameters such as the thrust force is obtained by solving the analyticalfield. A modular configuration for permanent-magnet pole is used to reduce teeth coggingforce. Furthermore, the manufacturing cost of TPMLMs can be reduced by using modular polepermanent-magnet. In this method, the width of permanent-magnets (PMs) is calculated by usingFourier analysis and a sensitivity analysis has been conducted to identify the robustness of thistechnique. Additional stator side methods are used to decrease the end face cogging force. Moreover,the stator teeth shifting method is proposed to reduce the electromagnetic force ripples. Also,the produced electromagnetic force of the machine is increased by using a delay in the power supply.3 -D non-linear finite-element analyses and experimental tests are performed to investigatethe effectiveness and performance of proposed techniques.

管状永磁直线电机的力脉动减小方法

本文介绍了一些新的方形截面管状永磁直线电机的力脉动减小技术。这些方法非常简单，因此在具有方形横截面的tpmlm中实现它们很容易。通过求解解析场，得到了推力等机床参数的解析形式。永磁极采用模块化结构，减小齿槽力。此外，采用模块化极永磁体可以降低tpmlm的制造成本。该方法采用傅里叶分析计算永磁体的宽度，并进行了灵敏度分析，以确定该技术的鲁棒性。采用附加的定子侧方法减小端面齿槽力。此外，还提出了定子齿移的方法来减小电磁力波动。此外，通过在电源中使用延迟，机器产生的电磁力也会增加。进行了三维非线性有限元分析和实验测试，以研究所提出技术的有效性和性能。
