SUMMARY
Using a Variable Frequency Drive (VFD) with an induction motor maintains constant flux by reducing voltage in proportion to frequency. While the torque available at various speeds remains relatively constant, the mechanical output power decreases as speed reduces, since power is the product of torque and angular velocity. Each motor has a specific V/Hz relationship curve that provides detailed insights into performance characteristics. A recommended reference for understanding this relationship is the Yaskawa document on motor performance.
