The main objective of this study was to model the operation of the induction motor as a generator. Using resources available in machines under maximum power of 180 W., The project was carried out through laboratory practices, which conducted several tests to measure parameters such as current, power, voltage and others, and then results were analyzed. The first part consisted on modeling the induction machine different operating conditions. Then a comparison in terms of efficiency between the motor and generator mode was assessed to determine the advantages and disadvantages of both. Finally, the induction motor as a generator at different speeds was examined and the speed and power output were obtained; this last one had the highest efficiency. The main findings were: to determine which mode is the most efficient engine in the induction machine, and it was found that the one for speeds greater than or equal in generating 1950 rpm tends to maintain efficiency by 70%. A difference between the equivalent circuit model and the real one at 20% in terms of efficiency was found
