- Calculation of the starting parameters for three-phase asynchronous motors is a very important issue as these parameters determine whether a motor can be satisfactorily used in a driving system and characterize it from the point of view of supply mains. The article discusses methods of determining initial starting current and initial starting torque with the omission of issues connected with electromagnetic transient processes, the influence of thermal states, and the effect of parasitic torques. Direct determination of these parameters is relatively complex, which is why they are often determined in an indirect way. Two methods are described, which allow to establish the aforementioned parameters: the tangent method and the short-circuit reactance distribution method. The methods consist in an extrapolation of short circuit characteristics obtained at reduced voltage. The results of research and the comparison of parameter calculations refer to two induction motors: squirrel cage and slip ring.
