Generalization of Maxwell Stress Tensor Method for Magnetically Anisotropic Regions
IEEE Transactions on Magnetics, 2019This article comments on the Maxwell stress tensor method for force calculation in magnetically anisotropic regions. Force acting on the magnetically isotropic region can be always represented by means of Maxwell stress tensor surface integral. However, the magnetic anisotropy causes the asymmetry of Maxwell stress tensor.

Quantum mechanics compatible Maxwell's stress tensor (presentation video)
Proceedings of SPIE, 2014There are many ways to calculate the optical forces acting on scattering particles such as Maxwell’s stress tensor, Lorentz forces, gradient and scattering forces, Lorenz-Mie formalism, T-matrix. All these approaches use the electromagnetic field and define the amount of linear momentum transferred to the scattering particles.

Force Calculation in 3-D Magnetic Equivalent Circuit Networks With a Maxwell Stress Tensor
IEEE Transactions on Energy Conversion, 2009Magnetic equivalent circuit (MEC) models are increasingly valuable for analysis and design of electromechanical devices, particularly electrical machines, because of their moderate computational effort and reasonable accuracy. Force and torque calculations in prior MEC implementations are almost exclusively based on the virtual work method (VWM ...

Implementation of Virtual Air-gap for Maxwell Stress Tensor
2006 12th Biennial IEEE Conference on Electromagnetic Field Computation, 2006In this paper, for the body force calculation of permanent magnet and ferromagnetic materials using Maxwell stress tensor method, an implementation of virtual air-gap is proposed. This scheme is simply performed in the post-processing stage. It is shown that the proposed virtual air-gap formulation for Maxwell stress is different from that for the ...

On-Load Back EMF of PMSM Using Maxwell Stress Tensor
IEEE Transactions on Magnetics, 2018This paper is focused on the on-load back-electromotive force (EMF) assessment in a permanent magnet synchronous machine (PMSM) using Maxwell stress tensor along with the frozen permeability method (FPM). Although the back EMF is only measured at open-circuit condition, it is known that the on-load back EMF is heavily affected by electric loading and ...

Separation of torque components using Frozen Permeability and Maxwell Stress Tensor
2017 IEEE Transportation Electrification Conference and Expo (ITEC), 2017Local force distribution in motors has been widely studied to analyze the origins of torque ripple and vibration. In most cases, there are multiple force waves which need to be identified and analyzed individually. While separation of these forces and the corresponding fields is simpler if the core is below saturation limits, special techniques are ...

Physical Review E, 2002
The Maxwell stress tensor (MST) T(M) plays an important role in the dynamics of continua interacting with external fields, as in the commercially and scientifically important case of "ferrofluids." As a conceptual entity in quasistatic systems, the MST derives from the definition f(M)def=inverted Delta x T(M), where f(M)(x) is a physically objective ...

Simple derivation of the Maxwell stress tensor and electrostrictive effects in crystals
American Journal of Physics, 1977Local equilibrium and energy considerations in an elastic dielectric crystal lead to a simple derivation of the Maxwell stress tensor in anisotropic dielectric solids. The resulting equilibrium stress–strain relations in the presence of electric fields are applied to determine the deformations of a charged parallel plate capacitor and to find the ...
