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.

Archive attached 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? `Your use of Yahoo! Groups is subject to the Yahoo! Terms of Service.`
