Theory and mitigation of motional eddy current in high-field eddy current shielding. [PDF]

open access: yesJ Appl Phys
Eddy current shielding by a Faraday cage is an effective way to shield alternating-current magnetic fields in scientific instrumentation. In a strong static magnetic field, however, the eddy current in the conductive shield is subject to the Lorentz force, which causes the shield to vibrate. In addition to mechanical issues (e.g., acoustic noise), such

Eddy current loss modelling for torque‐motors

open access: yesIET Power Electronics, 2022
A torque motor is a key component that directly influences the dynamic performance of two‐dimensional (2D) cartridge servo valves. Considering the effects of eddy current, a magnetic circuit model of a torque motor is proposed, and the eddy current ...

Application of Multiple Unipolar Axial Eddy Current Brakes for Lightweight Electric Vehicle Braking

open access: yesApplied Sciences, 2020
The braking system in a vehicle has the main role of slowing down the speed or stopping the moving vehicle. Compared to mechanical braking, which utilizes friction, non-contact braking has several advantages, including longer lifetime and less ...

Traditional Eddy Current–Pulsed Eddy Current Fusion Diagnostic Technique for Multiple Micro-Cracks in Metals

open access: yesSensors, 2018
Due to a harsh working environment, micro-cracks in metal structures (e.g., airplane, oil/gas pipeline, hydro-turbine) often lead to serious accidents, so health monitoring of the metals is of great significance to ensure their safe operation.

Eddy Currents and Corner Singularities [PDF]

open access: yesIEEE Transactions on Magnetics, 2012
Eddy current problems are addressed in this paper, in a bidimensional setting where the conducting medium is non-magnetic and has a corner singularity. For any fixed skin depth we show that the flux density is bounded near the corner, unlike the perfect conducting case.

Flow rate measurement in aggressive conductive fluids

open access: yesEPJ Web of Conferences, 2014
Two non-contact experimental methods of flow rate measurements for aggressive conductive liquids are described. The techniques are based on electromagnetic forces and Faraday’s law: Lorentz force is induced inside moving conductive liquid under influence
