提出了一种空中客车系统作为城市大众交通的一种替代方案。该系统的推进力由直线电机产生。有几种单面或双面线性电机拓扑结构可以采用，但由于其简单的被动轨迹和高的力密度值，双面线性感应电机（LIM）是首选。进行了一些研究工作，以开发分析LIM性能的分析模型。本文提出了一种准一维分析方法来分析电机性能，并考虑了纵向和横向边缘效应。通过分析结果与实验数据的比较，对所提方法的准确性进行了评价，结果显示出可接受的一致性。然后，针对期望的应用提出了电机设计，并通过有限元法和解析建模对其性能进行了评估。并给出了主要方程的推导。
An air-bus system is proposed as one alternative to urban mass transportation. The propulsive force of this system is generated by a linear motor. Several single- or double-sided linear motor topologies could be employed, but a double-sided linear induction motor (LIM) is preferred due to its simple passive track and high value of force density. Several research works were carried out to develop analytical models for the analysis of LIM performance. In this paper, a quasi-1-D analytical method is proposed to analyze motor performance, and the longitudinal and transversal edge effects are considered as well. Accuracy of the proposed method is evaluated by comparing the analytical results with the experimental data, which shows acceptable conformity. Then, the motor design for the desired application is presented and its performance is evaluated by both finite-element method and analytical modeling. Derivations of major equations are given as well.
