Variable speed applications often allow the use of smaller, less expensive pumps. Smaller pumps and selections right of BEP provide the best opportunity for energy savings at reduced speed (where the pumps run most of the time). Check NPSH margin for all selections, especially when selecting to . You can see that in every range; single phase V, 3 phase V, and 3 phase V, the S15 takes up considerably less of space than the S This very useful in applications where many drives are contained in a small amounts of space. Variable Frequency Drives Presented by: Greg Stark, P.E.

The motor shall require a load reactor and filters if the pump leads from the VFD exceed certain conditions. ENERGY SAVINGS Example: vfd for centrifugal pump  Flow is proportional to speed  Power varies to the cube of the speed change  20% reduction in speed = 50% reduction in energy  50% reduction in speed = 80% reduction in energy.3/5(2). Variable speed applications often allow the use of smaller, less expensive pumps. Smaller pumps and selections right of BEP provide the best opportunity for energy savings at reduced speed (where the pumps run most of the time). Check NPSH margin for all selections, especially when selecting to . Variable Frequency Drive (vfd) Cable - Discover Spark Box PPT Presentation Summary: A Variable Frequency Drive (VFD) is a type of motor controller that drives an electric motor by varying the frequency and voltage supplied to the electric. It varies both the frequency and amps of the AC waveform being delivered to the motor saving money in electricity. Basic components of a VFD: Input section, draws AC electric power from the utility, Rectifier section, converts the AC into DC power. Variable Frequency Drives Presented by: Greg Stark, P.E. September 10, Sponsored by: Variable Frequency Drives (VFD’s) • Popular speed control devices used in industrial, commercial and residential applications. –Huge energy savings potential operating centrifugal fans, pumps and compressors • Vary frequency of electrical.
