The paper presents a model of induction machines, in which saturation for both the main and leakage fluxes of individual windings is represented. The model operates with the real winding currents what gives a chance to model saturation of leakage magnetic circuits separately for each winding. The saturation of the main magnetic circuit is modelled by introducing a magnetising current denned analytically by all machine currents. Such a model allows to study the interaction of saturation of separately treated magnetic circuits of the main and leakage fluxes. Remarkable results of simulations are shown in the paper.
