This paper presents an analytical model of the electrical machine with permanent magnets submerged in ferromagnetic of rotor. This model has been prepared as a circuit model of electrical machine. The model takes into account a strong, local saturation of the magnetic circuit of the rotor. In the bibliography lacks a comprehensive development, enabling a transparent transition from the geometrical dimensions of the machine to a model useful to simulate its dynamic states. This mathematical formalism can be created only as a circuit model. Created a model not to be competitive against the finite element method. It allow to understand the interrelationship between design parameters and their effect on the properties and parameters of the machine. The verification of the model related to electromotive force induced in the various circuits of the armature. Verification of the parameters of the armature is planned in the future.
