Variable Frequency Drives (VFDs) in Process Equipment
Depending on the motor size, a VFD may be more economical than traditional soft start mechanical devices such as fluid couplings. As with a gradual start-up, the controlled shutdown provided by a VFD is also beneficial in minimizing mechanical shock. To Fine-Tune a Process. VFDs are also useful in fine-tuning a process during start-up.
