Magnetic field analysis of a coaxial magnetic gear mechanism by two-dimensional equivalent magnetic circuit network method and finite-element method

Magnetic Field Analysis of Lorentz Motors Using a Novel Segmented Magnetic Equivalent Circuit Method

A simple and accurate method based on the magnetic equivalent circuit (MEC) model is proposed in this paper to predict magnetic flux density (MFD) distribution of the air-gap in a Lorentz motor (LM). In conventional MEC methods, the permanent magnet (PM) is treated as one common source and all branches of MEC are coupled together to become a MEC network. In our proposed method, every PM flux so...

Two Dimensional Quasi Static Magnetic Field Analysis of SLIM using Adaptive Finite Element Method

The linear Induction motor, first conceived in the 19 century, could present a viable solution to the problem of quick and efficient transportation. However the performance of Single Sided Linear Induction Motor (SLIM) is severely degraded by ‘end effects’ and ‘transverse edge effects’. The present work is an attempt to investigate the magnetic flux distribution within the air gap and other reg...

A finite element model to simulate magnetic field distribution and laboratory studies in wet low-intensity magnetic separator

Low-intensity magnetic separators are widely used in the research works and the industry. Advancement in the magnetic separation techniques has led to an expansion in the application of this method in different fields such as enrichment of magnetic mineral, wastewater treatment, and medicine transfer in the human body. In the mineral processing industry, the main application of wet magnetic sep...

Three-dimensional calculations of the magnetic fields in a finite superconducting hollow cylinder in an applied axial magnetic field

In this study, a set of self-consistent coupled-integral equations for the local magnetic flux and current distributions in a finite superconducting hollow cylinder under an axial magnetic field has been directly derived by using the Biot-Savart law within the framework of the critical-state model. The equations were first solved numerically in the three-dimensional space before obtaining the h...
