Análisis y evaluación de la eficiencia energética en los motores eléctricos de los reactores de fabricación de resinas en una planta de pintura mediante la aplicación de Lean Manufacturing

Abstract

This research aims to explore the energy efficiency of the electric motors that power the mixing reactors in the resin manufacturing section of a paint production plant, proposing alternatives to optimize their operation in accordance with lean manufacturing principles. The study was conducted in a field environment using the hypotheticaldeductive method, allowing for observation of current behavior and the proposal of applicable technical options. Technical information was collected from five electric motors, and data collection tools were used with technical personnel in the area to complement the diagnosis. The results indicated that the motors operate at an average load factor of 70%, which shows room for improvement in energy efficiency and maintenance management. Based on this analysis, it was proposed to replace four of the five motors in the resin manufacturing area corresponding to processes 2, 3, 4, and 5 with Premium efficiency IE3 motors, capable of offering more efficient consumption and an estimated reduction of up to 14% in annual energy consumption. It was also recommended to ensure the continuity of improvements by applying lean manufacturing tools such as Total Productive Maintenance (TPM), VSM, and KPIs. These findings contribute to Sustainable Development Goal 7 and strengthen responsible energy management. This will allow for sustainable results over time and reinforce key operational practices within the production and maintenance areas.
