Аннотация: Linear induction MHD machines with a low-frequency power supply inverter form a complex of electromagnetic stirring of liquid aluminum in melting furnaces. The article discusses the classification features and characteristics of four-zone inductors of a longitudinal magnetic field with a two-phase power supply. To calculate the opeПоказать полностьюrating parameters of a linear induction MHD machine, a nonlinear multiphase model of a magnetic circuit was used. As a result of an iterative calculation, the distribution of the integral magnetic fluxes in the tooth zone of a flat inductor is obtained, and vector diagrams of electromagnetic regime parameters are constructed. The study shows the main directions of optimization of the low-pole induction machine mode to obtain the best current distribution in the windings and to estimate the equivalent linear current load. According to the results of the analysis, the main tasks and the sequence of stages of their solution were formulated when developing energy-efficient induction MHD machines of a longitudinal magnetic field.
