Semiconductor electrical energy converters are proposed, which can be used as electrical models of centrifugal pumps. The models take into account both the design features of the simulated object and the main indicators of the technological process, the study of which is carried out through the analysis of electromagnetic processes in the electrical model. The features of electromagnetic processes in the electrical model of a seven-blade centrifugal pump with a double-volute spiral outlet are considered. Therefore, the circuit of the electrical model under study consists of two halves, each of which contains seven branches, where the following are connected in series: a source of sinusoidal EMF, active resistance, inductance and diode. The output branches of the individual halves of the model have different parameters in accordance with the design features of the two-volute spiral branch. In their research, the authors departed from the traditional method of analysis, when electromagnetic processes are modeled by a system of differential equations with their solution by the classical method and subsequent determination of stable integrations by the fitting method. This approach turned out to be unacceptable due to the high order of the design scheme, therefore, in the study, the operator method for solving a system of differential equations compiled using the nodal stress method was used.
