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 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 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 ...

No-load copper eddy-current losses

Journal of the A.I.E.E., 1926
One of the factors which is sometimes responsible for very considerable losses in rotating machines is that of eddy-current losses in the copper conductors resulting from slot leakage flux produced by the main flux. These losses occur at no-load as well as under load and should not be confused with the copper losses resulting from the slot leakage flux

Eddy Current Losses in Conducting Slabs

IEEE Transactions on Power Apparatus and Systems, 1971
This paper considers the problem of calculating the eddy current losses in a rectangular conducting slab in a magnetic field which would be uniform if the slab were not present. The length axis is perpendicular to the uniform field, but there may be an angular displacement' about this axis.

Eddy current losses at cryogenic temperatures

IEEE Transactions on Magnetics, 1993
The effect of thermal processes on eddy-current losses in the structural elements of cryogenic and superconducting devices are analyzed. Maxwell's equations coupled with the heat-conduction equation are solved, taking into account the dependence of resistivity, heat capacity, and heat-transfer coefficient on temperature.

Intersheet eddy-current loss in laminated cores

Electrical Engineering, 1937
CORE LOSS in laminated structures subjected to an alternating magnetomotive force is made up of a hysteresis loss and an eddy-current loss. In modern power transformers the eddy-current loss is approximately 1/4 to 1/3 of the total loss.
