Levitation‒guidance‒propulsion integrated design for maglev trains based on oblique ring Halbach permanent magnet wheels

机车电传动, 2023
In this paper, a levitation, guidance and propulsion integrated design was proposed for maglev trains on the principle of permanent magnet electrodynamic suspension, in which the Halbach ring permanent magnet wheels and conductor plates were tilted after

Modeling, Design and Analysis of a Electrodynamic Levitation System by Considering the Skin Effect [PDF]

Journal of Intelligent Procedures in Electrical Technology, 2016
In this paper, lift and drag forces of permanent-magnet electrodynamic suspension (PMEDS) System have been studied by considering the skin effect. Electrodynamic suspension is based on repulsive force between two magnetic fields with the same polarity ...

Three-Dimensional Modelling and Validation for the Ultra-High-Speed EDS Rocket Sled with PM Halbach Array

Actuators
The ultra-high-speed rocket sled plays an important role in the ground test by simulating altitude flight. Rocket sleds can only be lifted for a short time with thermally uninsulated superconductors moving among an eddy-current-induced copper array.

A Novel Overlapped Compensation Structure and Its Effectiveness Verification for Expansion Joints in Plate-Type PMEDS Vehicles

Actuators
In the plate-type permanent magnet electrodynamic suspension (PMEDS) vehicle, expansion joints in discrete conductive plates trigger the eddy current truncation effect, thereby causing an attenuation in the levitation force.
