Resumen

The need for a lack of three-phase energy for the operation of an electric winch that is used to empty infrastructure constructions such as (houses, buildings, among others). The scientific article aims to replace the electric generator used in an electric winch for infrastructure construction, implementing the design of an electrical system through the use of a frequency inverter, this new alternative will reduce costs when using the electric winch. Analytical methods were used and it was checked in the Autodesk Inventor program, obtaining optimal results in the solution, the established methodology is technological-explorative, since the problem was identified, and the possible solutions had to be investigated, when establishing the new solution, it began to be designed and manufactured. Once completed, it was incorporated and assembled into the electric winch, where the respective tests were carried out, being effective at 95%, since the power of the network is unstable where there are ranges where the current is raised and lowered, being an inconvenience for the machine to work at 100%, but it is being used for different activities and needs in construction. The results obtained by adding up all the costs that concern each system of the electric winch for construction: the use of the electrical system is S/ 392.98, the use of the electric generator is S/ 831.60 per day and manually it is S/ 580.00 per day. In summary, by using a frequency inverter in the solution, it allows us to prolong the useful life of the motor, preventing deterioration and unnecessary stoppages that cause downtime, it helps us to reduce energy consumption with a more efficient use, matching the demand of the application, avoiding current peaks and voltage drops, above all, it allows us to regulate the frequency according to the need, configure the acceleration and deceleration to avoid stops and sudden starts of the engine.
