Model validation on no-load
The AIM had been applied to 12 different three-phase IMs from 0.75 kW to 15 kW (two-pole and four-pole motors), to calculate both the magnetization curve I10=f(E1) and the core losses on no load for various voltage levels.
The magnetization current is Iμ=Ilr and the no load active current Ioa is
