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 ...

Proposal of Maxwell Stress Tensor for Local Force Calculation in Magnetic Body
IEEE Transactions on Magnetics, 2018To investigate the noise reduction of an electrical machine, the deformation and vibration of the cores are evaluated by using the coupled magnetic and mechanical analyses [1]. In these analyses, the local force calculated by using the flux distribution obtained from the magnetic field analysis is required in the mechanical analysis. In the local force

Quantum mechanics compatible Maxwell's stress tensor (presentation video)
Optical Trapping and Optical Micromanipulation XI, 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.

Stress-tensor trace anomaly in a gravitational metric: General theory, Maxwell field
Physical Review D, 1977The renormalization of the vacuum expectation value of the stress-energy tensor of a scalar field propagating in a curved space-time with an arbitrary metric was discussed in a previous paper. A new regularization scheme was introduced which employs a continuation in the dimensionality of space-time implemented with a proper-time representation of the ...

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.

Force calculation by Maxwell stress tensor in 3D hybrid finite element-boundary integral formulation
IEEE Transactions on Magnetics, 1990The calculation of magnetic force by the Maxwell stress tensor in 3-D hybrid finite element-boundary integral formulation is presented. The Maxwell stress tensor is calculated on the boundary of the domain considered. One field component (tangential or normal depending on the use of the magnetic or the electric formulation) is calculated from the ...

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 ...

IEEE Transactions on Magnetics, 2013
Analytical modeling is still a very effective manner to calculate the magnetic fields in permanent magnet devices. From these magnetic fields, device quantities, e.g. force, emf or inductance, can be calculated. This paper presents a semianalytical technique, based on a 2D Fourier series to represent the magnetic field, to describe the force components

Calculation of Optical Force at Nanoscale Using Finite Element Method and Maxwell Stress Tensor
2019 International Applied Computational Electromagnetics Society Symposium - China (ACES), 2019The manipulations of nanoparticles based on the optical force can avoid mechanical damage to the targets, and the intensity of the optical force can be precisely controlled by the light source. In this paper, a numerical method combining finite element method (FEM) with Maxwell stress tensor (MST) method is presented to calculate the optical force ...
