“…9, the mixed 2D-3D FEM analysis method was used to analyze the characteristics of the LIM. Here, 3D FEM analysis is necessary for considering the transverse edge effect of the LIM [12][13][14]. In this study, 3D FEM analysis (using a onepole model as a 3D LIM model) was used to calculate an equivalent conductivity on the AL sheet by varying the overhang ratio on the secondary AL reaction plate.…”

-In order to develop a deep-underground great train express (GTX) in South Korea, the specifications decision and development of a traction control system (including an inverter and a traction motor), which considers a variety of route conditions, must be advanced. In this study, we examined the running resistance properties of a high-speed traction system based on a variety of tunnel types and vehicle organization methods. Then, we studied the power requirements necessary for the traction motor to maintain balanced speed in the high-speed traction system. From this, we determined the design criteria for the development of a high-speed traction system for use in the deep-underground GTX. Finally, we designed a linear induction motor (LIM) for a propulsion system, and we used the finite element method (FEM) to analyze its performance as it travelled through deep-underground tunnels.

“…Several researchers in the past have developed proper modeling techniques to analyze and explain the end effect, and some of these have proposed additional hardware to compensate for the flux at the entry part [7]- [16]. Although their proposed methods seem plausible, the installation of the additional part may be too difficult to practice.…”

-The end effect of a linear induction motor (LIM) has been known for several decades, especially in high speed operation. The exit part of the primary is not dealt as extensively as the entry part because of its minor effect. However, the exit part is one of the keys to weaken the dolphin effect, which occurs in high speed operation. In this paper, the concept of the virtual primary core is introduced, and chamfering of the primary outlet teeth is proposed to minimize the longitudinal end effect at the exit zone. For this, LIM for the high-speed train is designed and analyzed by using finite element method. Results confirm that chamfering can improve thrust performance effectively.

“…LIMs' widest applications are in transportation systems. Industrial tests, like accelerating aircrafts and manufacturing processes, like machine tools are the other important utilizations of LIMs [1], [2]. This broad range of applications has attracted research attentions and several papers have focused on LIMs [3]- [9].…”

In this paper, design and optimization of a ladder-type single-sided linear induction motor (Ladder SLIM) for machine tool applications is investigated. High-speed linear induction machines suffer from the end-effect phenomenon, which can reduce the thrust and result in declined output characteristics. Although it is common to consider this phenomenon in high-speed applications, it is essential to take it into account in the design and analysis of low-speed low-air-gap linear machines. In addition, Ladder SLIMs have significant flux density ripples, and using skewed bars for secondary of the machine is a common solution for it. Therefore, providing required equations, an algorithm for designing a Ladder SLIM considering the end-effect phenomenon based on Duncan model is proposed, and effect of several design parameters on the output characteristics are analyzed. In order to find the optimum design parameters, a multiobjective optimization problem considering efficiency, power factor, and braking force due to the end effect is defined. This problem is optimized with two algorithms, interior point and genetic algorithms, and results are compared. Finally, the validity of the obtained solution is verified using a 2-D and 3-D time-stepping finite-element method. Index Terms-End-effect braking force (EEBF), genetic algorithm (GA), interior point algorithm (IPA), ladder-type single-sided linear induction motor (Ladder SLIM), multivariable multiobjective (MVMO) optimization, time-stepping finiteelement method (TSFEM). 0885-8969 . Her research interests include design, optimization, and performance analysis of electrical machines and electromagnetic sensors.
