AB - <strong><em>Aim</em></strong><em>. Development of</em><em> </em><em>a method for calculating mechanical</em><em> characteristics of three-phase induction motors with single-phase power supply. <strong>Methods</strong>. The developed algorithm is based on the high-adequacy mathematical model of motor and projection method for solving the boundary problem for equations of electrical circuits balance presented in the three-phase coordinate system. As a result of asymmetry of power supply to the stator windings, in steady state, flux-linkage and current change according to the periodic law. They are determined by solving the boundary problem. <strong>Results</strong>. The developed mathematical model allows determining periodic dependence of coordinates as a function of slip and, based on them, mechanical characteristics of motors. <strong>Academic novelty. </strong>The developed method relies on a completely new mathematical approach to calculation of stationary modes of nonlinear electromagnetic circuits, which allows obtaining periodic solution in a timeless domain. <strong>Practical value. </strong>Using the developed calculation algorithm, one can select capacitance required to start an induction motor with single-phase power supply and calculate static mechanical characteristics at a given capacitance. </em>
