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.

Persistent Current Analysis of Superconducting Coils in an Electrodynamic Suspension System

Electrical Engineering in Japan, 1994
AbstractIn a superconductive electrodynamic suspension system, superconducting coils experience a space harmonic magnetic field generated by induced current in the levitation coils installed along the guideway. Current in a superconducting coil varies to keep the total magnetic flux constant when the coil is exposed in an external magnetic field ...

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.
