Pseudo-Three-Dimensional Analytical Model of Linear Induction Motors for High-Speed Applications

Mario Paolone, André Hodder, Lucien André Félicien Pierrejean, Simone Rametti

Literature on linear induction motors (LIMs) has proposed several approaches to model the behavior of such devices for different applications. In terms of accuracy and fidelity, field analysis-based models are the most relevant. Closed-form or numerical so ...

Crystallization of Size-Selective Nanopores in Graphene for Gas Separation

Nanoporous single-layer graphene (N-SLG) membranes, owing to their single-atom thinness, have the potential to exceed the permeance and selectivity limits of gas separation membranes. However, two key issues in the top-down N-SLG synthesis need to be addre ...

Leakage Flux Modeling of Multi-Winding Transformers for System-Level Simulations

Drazen Dujic, Min Luo, Jost Allmeling

In multiwinding transformers, different geometry of the individual windings leads to unbalanced leakage flux paths. The unbalance affects the behavior of the power electronic converters, where these transformers are used. This paper proposes an approach to ...

Adsorptive Removal of Pb(II) and As(V) from Aqueous Solution by PVDF/HMO Ultrafiltration Mixed Matrix Membrane

Younes Lucas Seghrouchni

Lead and arsenic are among the designated chemicals of major concern by the World Health Organization, they affect millions of people worldwide with both acute and chronic effects on human health. In the current study, mixed matrix membranes (MMMs) were fa ...

Leakage Flux Modelling of Multi-Winding Transformer using Permeance Magnetic Circuit

Drazen Dujic, Min Luo, Jost Allmeling

The size and position difference of the windings determine the leakage flux path and give rise to unbalance of the short-circuit impedances, which strongly affects the transient behaviour of the transformer. This work proposes a new approach of modelling w ...

Permeance Based Modelling of the Core Corners Considering Magnetic Material Nonlinearity

Drazen Dujic, Min Luo

Lumped magnetic circuit provides possibility for fast transient simulation of magnetic component together with power electronics circuit. The simplified geometry representation however is not able to completely reflect the real field distribution, especial ...

What We Can Learn about Business Modeling from Homeostasis

Gil Regev, Alain Wegmann

Business modeling methods most often model an organization’s value provision to its customers followed by the necessary activities and structure to deliver this value. These activities and structure are seen as infinitely malleable; they can be specified a ...

Combined Analytical-Numerical Approach for the Modeling and Analysis of Threephase Transformers.

Jean-Jacques Simond, Basile Kawkabani, Gilles Rosselet

This paper deals with a combined analytical-numerical approach for the study of the steady-state and transient behaviour of three-phase transformers. This approach based on magnetic equivalent circuits, takes into account the nonlinear B-H curve. The nonli ...

Analytical formula for rotating motor permanent magnet MMF in a general case

Yves Perriard, Marcel Jufer, Miroslav Markovic

This paper presents an analytical formula for the permanent magnet (PM) magnetomotive force (MMF) in a slotted PM rotating motor. To derive this formula, an analytical 2D solution of Poisson's equation for the equivalent slotless configuration using the Fo ...
