OPTIMIZATION OF ENERGY EFFICIENCY IN ELECTRIC MOTORS
Abstract
Electric motors are responsible for a significant portion of global industrial energy consumption. This study explores advanced methods for optimizing energy efficiency in electric motors, including the use of high-efficiency motor classes (IE3, IE4), variable frequency drives (VFD), intelligent monitoring systems, and predictive maintenance strategies. The research evaluates both technical and economic impacts, demonstrating that optimized motor systems can significantly reduce energy consumption, operational costs, and environmental impact.References
