Abstract
This article discusses a variable‐frequency drive (VFD) generator that matches pump motor speed with flow or demand to save energy and reduce stress on rotating components. The article discusses how a VFD can control motor speed by changing the frequency that affects the pumping rate, along with affinity laws for centrifugal pumps, relationships between pump speed and frequency, starting a motor by using a VFD, energy savings, and special emergency applications. The article contains two insets, one that explains how VFDs control small generators and one that details how the city of Naples, Florida, constructed a mobile 15‐kW trailer‐mounted generator, a VFD, and a level transducer.
