Comparison of permanent magnet configurations of an electrodynamic suspension integrated in a small-scale test vehicle

Electrodynamic suspensions are well-suited for high-speed maglev systems. This paper optimizes and compares two configurations of permanent magnets of such suspension integrated in a small-scale test vehicle.

Stability of a 4 degree of freedom rotor on electrodynamic passive magnetic bearings [PDF]

, 2014
Electrodynamic bearings exploit repulsive forces due to eddy currents to produce positive stiffness by passive means without violating the Earnshaw stability criterion.

Time Varying Behavior of the Loudspeaker Suspension

, 2007
The suspension part of the electrodynamic loudspeaker is often modelled as a simple linear spring with viscous damping, however the dynamic behaviour of the suspension is much more complicated than predicted by such a simple model.

Axial electrodynamic suspension for a vertical axis rotor: modeling and experimental validation

, 2011
Eddy current effects are the base of electrodynamic bearings principle. They arise when a conductor moves in a magnetic field. As they are passive by nature, no additional instrumentation such as sensor or power electronics are needed, and this implies ...

A hybrid electrodynamic vibration harvester

, 2007
A vibration harvester has been designed, combining an electrodynamic transducer with a micromachined resonator. The transducer consists of 8 off-the-shelf NdFeB magnets floating above a series of copper coils.

Study on electrodynamic suspension system with high-temperature superconducting magnets for a high-speed maglev train

, 2019
For the electrodynamic suspension (EDS) system in the high-speed magnetic levitation (Maglev) train, high-temperature superconducting (HTS) coils made of ReBCO-coated conductors can be used as levitation magnets.

Summary of a Bearingless Motor with Passive Electrodynamic Axial Suspension

Summary of a Bearingless Motor with Passive Electrodynamic Axial Suspension
Either active control or passive stabilization can be used to achieve non-contact magnetic sus-pension in magnetic bearings and bearingless motors. As the rotational speed is increased, the d-axis current becomes harder to regulate, thus motivating the research of full passive suspension. Permanent magnet bearings and reluctance forces cannot stabilize
