> Hello,

> I watch your simulation, I think that your problem is thickness of laminations of steel, it is a parameter important when work with frequency for eddy currents in the laminations, if you don't put this parameter the laminations is considered as a core. This parameter is d(lam) in toolbox of material properties. Why do you put currents in rotor? If the current is induced in the rotor.
