Re: [femm] Jiles-Atherton Model Parameters for Alnico5

["Robert Macy" <macy@xxxxxxxxxxxxxx>]

Any input? Don't have experience with alnico.

However......

PSpice uses Jiles-Atherton modeling. Tried to do some circuit simulations
using "square" hysteresis core materials with results which never came close
to measured values. Off by more than magnitudes. Could never get *any*
coefficients into the jiles-atherton model to work. Finally had to make my
own.

In other words, be very careful of your model. Make certain your modeling
follows the real world.

Hi:

I am working on a device based on permanent magnets, in specific I am
using an arrangament of Alnico5 PM's. To properly model the
hysteresis behavior of any PM is necessary to use an analytical
magnetic hysteresis model. Well, I have chose the Jiles-Atherton
model; and, I am wondering if somebody from this list have already
identified the parameters associated with the Jiles-Atherton for
Alnico5.

Any input would be very helpful.
