Abstract

Variable frequency speed regulation technology achieves speed adjustment by changing the motor supply frequency, demonstrating significant energy-saving potential and stability advantages in motor control systems. The research focuses on its energy-saving effect and operational stability, analyzes the impact mechanism of technical principles on energy consumption, and explores the differences in energy-saving rates under different operating conditions and the optimization path of key parameters. In response to stability issues caused by voltage fluctuations and sudden load changes, the synergistic effect of control algorithms and hardware configurations is studied. The results show that proper application can increase the energy-saving rate of the motor system by 20%-40%. Dynamic adjustment strategies can effectively suppress speed fluctuations, providing theoretical and technical support for the efficient and stable operation of industrial motors.
