N2 - Currents, losses, winding and iron core forces at no-load of saturated three-phase induction machines are determined based on a nonlinear magnetic field analysis. Instantaneous magnetizing currents are calculated for given balanced sinusoidal and nonsinusoidal terminal voltages. Subsequently, the harmonic components of the magnetizing current and the induced voltage are obtained from a Fourier analysis. The core-loss current component is derived from the sum of local core losses and the no-load current is then iteratively obtained from the sum of the magnetizing and the core-loss current components. Finally, the calculation of winding and iron-core forces is derived from surface integrals. Part II deals with the results that are based on this analysis.
