A recent trend in nuclear power plant upgrades has been the replacement of the motor-generator (MG) sets that drive the reactor circulating pumps with variable-frequency drives (VFD). Siemens’ first ...

Single VFDs are often integrated into new and existing applications due to the huge amount of energy savings and programming benefits. Specialty pump drives often go above and beyond the requirements ...

Beyond the wheel, the most important mechanical equipment serving humanity is the centrifugal pump. Centrifugal pumps make modern quality of life possible. Turn on a faucet and a centrifugal turbine ...

It is interesting to look at figures from the Energy Information Administration about where energy gets consumed in our economy. These figures reveal that industrial uses account for 31% of all energy ...

Honeywell and Danfoss are partnering to integrate variable frequency drive (VFD) technology with Honeywell's Experion Process Knowledge System platform to streamline motor control, reduce energy ...

A Variable Frequency Drive (VFD) regulates the speed of a 3-phase AC electric motor by controlling the frequency and voltage of the power it delivers to the motor. These devices, also known as ...

As the cost of components and pumps becomes more affordable, variable speed pumps are being used to increase the efficiency and reliability of water distribution systems in multi-story buildings.
