“…The magnets establish an electric field that prevents contact between the pods of trains even during power outage to ensure that they are still hovering. Consequently, this is a reasonable and secure levitating mechanism for swift transportation systems like Hyperloop [4].…”

The project is centered on the development of an Hyperloop prototype magnetic levitation system, it harnesses the repulsive forces of permanent magnets to achieve magnetic levitation. It also incorporates a comprehensive review of maglev and hyperloop system technology, exploring their development and applications. The utilization of Aerodynamic technology in designing the capsule structure to facilitate smooth and efficient movement within the hyperloop. Applying the suction force of a vacuum cleaner to move the capsule easy and also conventional method of propulsion is implemented in the project. The challenges in the hyperloop prototype is to develop economical, energy-efficient, and environmentally friendly method of transportation for passengers without relying on fossil fuels or causing a significant carbon footprint in real-time.

“…Although hyperloop technology supports a grand vision of human connectivity and efficient travel, few analyses have been conducted on secondary propulsion systems for hyperloop applications [2], [3]. Primary propulsion systems are active for the majority of a hyperloop trip and transport the pod over long distances at high speeds whereas secondary propulsion systems are active for a short duration at the start of a hyperloop trip and are designed to accelerate the pod to high velocities over short distances before the primary propulsion systems activate [4]. We propose a railgun accelerator system as a novel form of secondary hyperloop pod propulsion.…”

Secondary propulsion methods for high-speed hyperloop transportation are sparsely researched. Secondary propulsion methods are essential to quickly, efficiently, and safely get a hyperloop pod up to its target speed from a stationary state. In this paper, we propose and analyze the feasibility of a form of electromagnetic secondary hyperloop propulsion, called a railgun, commonly used in modern-day artillery technology for high-speed ammunition launching. We assess the feasibility of two different materials and three different geometries for a railgun armature to propel a hyperloop pod. Inverse design of multiphysics simulation of multibody dynamics, magnetic fields, and electric currents are used for material selection of the armature that minimizes rail current energy requirements and the armature geometry that maximizes structural integrity.

“…The utilization of linear induction motors (LIMs) is considered an effective approach to produce frictionless propulsion. LIMs don't require the use of Permeant Magnets (PMs) to operate avoiding the increment of weight and cost of the MAGLEV system [1]. Available publications about LIMs are very diverse and mostly written for a particular LIM with a specific operation [2].…”

Through electromagnetic forces, linear electric (electromagnetic) machines (LEMs) enable the direct conversion of electrical energy to linear motion mechanical energy (or vice versa). In industry, linear motion is particularly prevalent. LEMs were created in the nineteenth century, but they weren't widely used in industry until 1960 since control required power electronics (in the absence of any mechanical transmission). However, LEMs require power electronics for linear position, speed, and/or force control in order to perform better than rotary electric motors with mechanical transmission. After 1960, LEMs have steadily improved. The levitation and drive forces in the two-phase Linear Induction Motor (LIM) is be controlled by changing the phase angle between two phases. This paper derives the flux density in the air gaps, the secondary current density, driving and levitating force density. The slotted stator is replaced in the model by a smooth surface stator having a continuous current sheet represented by the stator electric loading AS (x, t) = Re\(\left\{\sum _{\varvec{m}}{\underset{\_}{\varvec{A}}}_{\varvec{s}\varvec{m}}{\varvec{e}}^{\varvec{j}(\varvec{w}\varvec{t}-{\varvec{a}}_{\varvec{m}}\varvec{x})}\right\}\) . corresponding to a stator current Is flowing in the z-direction. The secondary current is assumed to be still flowing only in the z-direction. It closes its paths through the stator ends at both sides of the active length. Hence both the magnetic field intensity H and the magnetic flux density B have x-component and y-component. Average Force equations are derived by taking the summation of the force density over the secondary length using two-dimensional field analysis are used to simulate the performance of Linear Induction Motor. It is investigated the effects of phase angle change on the secondary current density, normal and on the tangential flux density components. Also, this phase shift effects are extended to include the two components of the force (Levitation and Driven). The calculations are performed and plotted by using MATLAB program.
