Eddy current losses in ferromagnetic laminations

Journal of Applied Physics, 2000
It is demonstrated through the comparison of analytical, numerical, and experimental results that the existence of excess eddy current losses can be explained by the peculiar nature of the nonlinear diffusion of electromagnetic fields in magnetically nonlinear laminations. The essence of this peculiar nature is that nonlinear diffusion occurs as inward

Eddy Current Loss Calculation for Permanent Magnet Eddy-current Coupler

2020 7th International Conference on Information Science and Control Engineering (ICISCE), 2020
This paper presents an analytical method for calculating the eddy current loss of permanent magnet eddy-current coupler (PMEC). A magnetic equivalent circuit (MEC) model considering the eddy current effect and leakage is established. Then, based on Kirchhoff’s law and Ampere’s law of loop, the flux density passing through the conductor rotor and the ...

Eddy-Current Losses in Mn-Zn Ferrites

IEEE Transactions on Magnetics, 2014
We predict the contribution of eddy currents to power losses in polycrystalline Mn-Zn ferrites and apply it to experimental results obtained on a broad frequency range in different commercial materials and differently sized ring samples. It is verified by theory and experiment that the eddy currents can, in sufficiently large specimens, measurably ...

Eddy current and hysteresis losses in ferromagnetic media

IEEE Transactions on Magnetics, 1998
This paper is a contribution to the evaluation of losses in ferromagnetic media, due to eddy currents and magnetic hysteresis, the field source being the time harmonic induced e.m.f. The fundamental field equations are solved numerically by using a finite element formulation, corresponding to the space discretization, and a second order trapezoidal ...
