Abstract

Inverters have enormous energy-saving potential in mechanical transmission, and their effects depend on the coordinated matching of control parameters and load characteristics. Currently, most systems have high speed-regulating energy consumption due to extensive parameter settings, making it difficult to exert their energy-saving advantages. Focusing on improving energy-saving effects, this paper deeply analyzes the influence mechanism of inverters on motor power, torque, and efficiency under different working conditions, and reveals the energy-saving paths of key parameters such as frequency regulation, acceleration/deceleration time, and voltage-frequency curves. It proposes a parameter optimization strategy based on load characteristics to accurately match the actual needs of the system and achieve optimal energy efficiency. The research proves that scientific parameter setting can significantly reduce invalid energy consumption under light load and variable load, effectively improve the overall operating efficiency, and provide a theoretical basis and practical direction for energy conservation of industrial equipment.
