“…Equation (20) describes the factor that the secondary width is properly wider than the primary one in consideration of the working stability of metro. Equation (21) is the constraint of the primary length in account of motor cost and performance, and (22) is the limitation of primary current density in case of overheating, which is chosen according to Refs [12], [16].…”

“…In order to attain better drive performance, i.e. higher efficiency and power factor, Refs [12]- [16] have done plenty of work to model the SLIM first, and then continue to make design and performance analysis. Unfortunately, these studies either fail to fully consider the coupling relationship between different structure parameters, or fail to align proper constraints for SLIM to meet the rated working conditions.…”

Single-sided linear induction motors (SLIMs) have been increasingly developed in industries in the past ten years, especially in transportation systems. This is basically due to their merits of direct thrust, high acceleration and deceleration, less mechanical loss, etc. However, for the SLIMs special physical structure, including the cut-open magnetic circuit, different width between primary and secondary (along the axial direction), they suffer from longitudinal end-effect and transversal edge-effect, which would make their mutual inductance and secondary equivalent resistance change unregularly, and hence increase the complexity of their equivalent circuit model (ECM). Meanwhile, for the influence by skin effect resulted from the secondary eddy current, the resistance of secondary back-iron, etc., the SLIMs are inherited by seriously partial electromagnetic saturation or nonlinear effect particularly in large current excitation condition, and their accurate ECM are difficult to get, which might bring great difficulty to their electromagnetic design and performance analysis. In this paper, first, one improved ECM that fully considers longitudinal end-effect, transversal edge-effect, skin effect and electromagnetic saturation of secondary sheet back-iron, is presented. Second, the influence of different structure parameters on SLIM key drive indexes, e.g. thrust, efficiency and power factor, is analyzed. Third, a multi-objective optimization function is established based on genetic algorithm (GA), which aims to increase the efficiency, power factor and thrust as well as to reduce primary weight simultaneously.Index Terms-Single-sided linear induction motor (SLIM), equivalent circuit model (ECM), genetic algorithm (GA), drive performance, multi-objective optimization function.

-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.

Unfortunately, these works either fall short to consider the coupling relationship among all structure parameters fully or fail in aligning proper constraints to meet the standard working conditions [23].…”

This paper investigates the design and implementation of single-sided linear induction motor towards determining the end effect intensity, reduces the primary weight of the system and improves the efficiency by multi-objective optimisation approach. This optimisation technique is a combination of genetic with cuckoo search (GCS) algorithm is introduced to improvise the efficiency and power factor, as well as to minimize the end effect intensity, simultaneously. The performance of the designed novel approach will be validated based on the measure of different parameters such as Efficiency, Power factor, Maximum thrust slip, Aluminum thickness, Primary width/pole pitch, Primary current density and the braking force due to the end effect. Finally, to validate the optimisation results, 3D finite element method is employed and compared the results with the existing technique like GA, PSO, and Cuckoo search.
