As far as I understood, in this model no rotor
currents are applied. Is this on purpose to calculate something else (for
example magnetizing inductance) or by mistake? Regardless of the reason, I have
another question: Can FEMM calculate rotor currents by using only stator
currents and slip frequency? If the answer is no, then how can we know the rotor
bar currents to be applied for a three phase squirrel cage induction
machine? And of course what will be the current distribution among the rotor
bars?
P.S: I need the currentconstraint.pdf file. What is
the address of this file? Thanks.

Hi everybody¡
In the program femm how could we force the
program to use the non-linear B-H curve to simulate the motor at f=0.02
Hz
This kind of problem is time-harmonic analysis.

How could we calculate losses by eddy currents
and hysteresis? I did two runs as you said, for rotor losses at 0,5Hz andfor
the stator losses at 50Hz multiplying the resistivity of all materials of
rotor bay 100, but the losses are very small. Can affect the linearity tothe
solution?
