This article presents a theoretical study of the electromechanical characteristics of a squirrel-cage induction machine operating in generator mode. A 1.5 kW Siemens induction motor was selected as the research object. The parameters of the T-shaped and Г-shaped equivalent circuits were determined based on no-load and short-circuit tests. The dependence of electromagnetic torque on rotor slip for both generator and motor operating modes was calculated, and the corresponding mechanical characteristics were obtained. The results showed that the critical torque in generator mode is higher than in motor mode. The obtained results can serve as a theoretical basis for evaluating the application of induction generators in micro-hydropower plants and autonomous energy systems.
