Magnetic levitation - Wikipedia
Maglev, or magnetic levitation, is a system of transportation that suspends, guides and propels vehicles, predominantly trains, using magnetic levitation from a very large number of magnets for lift and propulsion.
How Rotation Drives Magnetic Levitation - Physics
2023年10月13日 · The Levitron toy, for example, is a magnetic top that is spun by hand and then placed above a magnetic plate that exerts a repulsive upward force on the vertically oriented top. A unique mechanism appears to be behind the new levitation, first demonstrated in 2021 by Hamdi Ucar, an electronics engineer, then at Göksal Aeronautics in Turkey [2].
Three-Dimensional Active Magnetic Levitation Actuating and
2024年11月24日 · A three-dimensional active maglev (magnetic levitation) actuating system based on force imbalance is proposed. By combining the principle of force imbalance control with the control algorithm, the stable levitation and controllable levitating …
Magnetic levitation by rotation | Phys. Rev. Applied
2023年10月13日 · Based on theoretical arguments and a numerical model, we show that a constant vertical field and eddy-current-enhanced damping are sufficient to produce levitation from rest. This enables a gyroscopically stabilized counterintuitive steady-state moment orientation and the resulting magnetostatically stable midair equilibrium point.
The Effect of Magnetic Field Distribution and Pole Array on the ...
2015年3月30日 · It was shown in this study that the vertical levitation capability and stability of Maglev systems can be improved depending on the cooling regime, pole number, and suitable arrangement of the PMG. In this paper, it was shown that when the pole number increases, the levitation force density increases.
Magnetic Force Performance of Hybrid Multisurface HTS Maglev …
Abstract: The vertical levitation force, guidance force, and magnetic stiffness values, and thus the loading capacity and movement stability of high-temperature superconducting (HTS) Maglev systems, are aimed to be increased in this study by using auxiliary permanent magnets (PMs) in the onboard unit together with the multisurface HTS-permanent ...
Analysis of the magnetic levitation characteristics of the vertical ...
2024年9月6日 · In this paper, we explore the variation of electromagnetic force as a vertical toroidal Halbach permanent magnet rotor (THPMR) approaches a conductive plate. Theoretical and experimental studies are performed to establish a levitation model of the THPMR. We focus on the magnetic field distribution of the rotor and the value of the repulsive force.
detail the procedures generally used for measuring the vertical (levitation) and the lateral (guidance) forces in magnetic levitation and the results obtained from experiments. We detail and give a critical review of the various models proposed for reproducing the force measurements.
Superconducting Levitation in a Gap Between Two Magnetic …
2022年11月4日 · The vertical stability of levitation and the resulting distributions of induced currents in an HTS volume were also analyzed. It is shown that the configuration with HTS levitation between two PMs with oppositely directed magnetizations produces a much higher lift force than traditional levitation systems.
Vertical–Lateral Coupling Force Relation of the High-Temperature ...
2020年8月7日 · In this article, an experiment was designed to study the vertical-lateral coupled effect of the levitation and guidance force. A 2-D coupling model was proposed to fit the experimental data. Furthermore, the motion stability and the dynamical characteristics of the HTS maglev system in 2-D space were studied.
