FIELD: electric drives for electrified transport, mechanical engineering, and metallurgy. SUBSTANCE: classic equivalent T-circuit of induction motor phase is employed. Stator current, magnetization, and supply voltage signals are generated using new expressions. Analytic model of reference induction motor is devised. Method provides for evaluating adjustable variables of induction motor including saturation current, electromagnetic moment, and rotor speed within comprehensive range of sampling steps. Method may be found useful for vector control systems, for investigating transient operating conditions of induction motor, as well as for control systems, analytical synthesis of speed governors, and for electric drive adjusting devices. EFFECT: improved accuracy of evaluating controlled variables, enlarged functional capabilities. 3 cl, 25 dwg
