Research on Braking Performance of a Novel Variable Magnetic Circuit Eddy Current Retarder

IEEE Access
To address the limited braking performance of conventional eddy current retarders (ECRs) over the full speed range, a novel variable magnetic circuit eddy current retarder (VMCECR) is proposed by integrating alternating magnetic field braking and ...

Research on permanent magnet reduction gear for trams

机车电传动, 2022
As a ground transportation, the tram needs frequent speed regulation. Relying on mechanical braking when decelerating will cause excessive wear of the mechanical devices.

A Novel Approach on the Unipolar Axial Type Eddy Current Brake Model Considering the Skin Effect

Energies, 2020
The braking torque mathematical modelling in electromagnetic eddy current brake (ECB) often ignores the skin effect that occurrs during operation. However this phenomenon can not be simply neglected. Therefore, this paper presents a mathematical model of

Analysis of linear eddy current brakes for maglev train using an equivalent circuit method

IET Electrical Systems in Transportation, 2021
An equivalent circuit method (ECM) is developed to analyse the linear eddy current braking system (ECBS) of the maglev train. The distribution of eddy current in the rail is represented by dividing the rail into a series of small segments in which the ...

Impact of recurrent dehydration with mild periodic water restriction on blood pressure and renal function in male spontaneously hypertensive rats

Experimental Physiology, Volume 111, Issue 7, Page 3398-3411, 1 July 2026.
Abstract The kidneys regulate fluid balance but are susceptible to adverse effects of inadequate hydration. Epidemiological studies have linked low water intake to renal dysfunction and chronic kidney disease. Previously we showed that restricting water intake to a single 2‐h period daily for 4 weeks promotes hypertension as well as renal inflammation,

Analytical Model for a Permanent Magnet Eddy-Current Brake With Transverse Edge Effect

IEEE Access, 2019
In this paper, the analytical model of a permanent magnet (PM) linear eddy current brake is presented with consideration of transverse edge effects. The transverse edge effects can be divided into static and dynamic effects.

Multiobjective Optimization of Hydrogen‐Assisted Calophyllum inophyllum Biodiesel Operation in a Compression Ignition Engine

Energy Science &Engineering, Volume 14, Issue 6, Page 2897-2929, June 2026.
Tri‐fuel diesel–Calophyllum inophyllum biodiesel–hydrogen operation was tested over 96 points in a diesel engine. Eight performance and emission metrics feed a preference‐agnostic Bootstrapped Empirical Multiobjective Ranking and Selection methodology, revealing load‐blend‐hydrogen windows that increase efficiency, restrain smoke, and expose NOx trade ...

Effects of Rotor Material on Eddy Current Brake Performance

European Mechanical Science, 2017
The eddycurrent brake(ECB) is built by corresponding motion between a coil and a metallicmaterial. The eddy current and coil creates reverse magnetic fields w producesbraking force and dissipated heat due to resistivity of rotor material.

A fully-discrete finite element approximation for the eddy currents problem

Ingeniería y Ciencia, 2013
The eddy current model is obtained from Maxwell’s equations by neglecting the displacement currents in the Amp`ere-Maxwell’s law and it is commonly used in many problems in sciences, engineering and industry (e.g, in induction heating, electromagnetic ...

The Dilution Paradox in Extracellular Vesicle Flow Cytometry

Journal of Extracellular Vesicles, Volume 15, Issue 6, June 2026.
ABSTRACT Concentrations of extracellular vesicles (EVs) can be measured by flow cytometry, which detects fluorescence and light scattering signals from single particles. To ensure single particle detection, plasma samples are diluted based on their particle concentration, which can differ 100‐fold between samples.
