How to calculate skin and proximity effect

Hi,

I can see in the features segment that we can calculate skin and proximity effect of windings. But I am not able to find any document or design example of how todo so.

Thanks in advance :)

    Hi,

    To compute the skin depth and proximity effect in Flux, in the case of transient application you need to represent each strand and insulation inside the slot. In the case of steady state AC application you can use the equivalent region (coil conductor region with losses) to take into account of the skin and proximity effect.

     

    Best regards.

    Hi there,

    It is easy to estimate the skin depth that you need for your application if you are using Flux solver. In order to get to know how fine your mesh need to be at the boundary, you can access the skin depth computation calculator by going to mesh>skin depth computation. Just use the resistivity, relative permeability and freq. of your application and you will get an estimation of the skin depth (1 skin depth).

    If you are working in a 2D representation, you can access to the meshskineffectfaceregion Macro that will make your life easy trying to setup the mesh at the estimated skin depth.

    Hope this comment helps!
