Utility power plant generators are usually designed for a power factor (PF) of .8 to .9. If demand-side PF is lower than the designed PF, the generator current will rise above the equipment's rated ...

Variable speed drives (VSDs), sometimes also known as variable frequency drives, are electronic devices used to regulate the speed of an ac induction motor. Electric motors consume approximately 25% ...

Single- and three-phase alternating current (AC) motor speed can be controlled by controlling the frequency of the voltage coming to it. Motor speed has a lot to do with the capacity of refrigeration ...

Speed optimization features also improve productivity, as do remote operator interfaces that link and coordinate multiple drives. What can designers do to ensure higher productivity from the ...

Energy efficiency was key at a new underground treatment plant in Finland. Stephen Takhar, managing director of Vacon UK, explains how variable speed drives helped the client take control and reduce ...

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 ...

When Tesla first introduced the 3-phase alternating current (AC) induction motor in 1888, he knew that his invention was more efficient and reliable than Edison's direct current (DC) motor. However, ...

Variable frequency drives (VFDs), also known as variable speed drives (VSDs), are used to modulate the speed of motors in various applications, from hydronic water pumping to VAV fan units to vacuum ...

Finland-based Danfoss Drives is supplying variable-speed AC drives for the propulsion systems of the Finnish Navy’s four Pohjanmaa-class multi-role corvettes. Part of the Finnish Defense Squadron 2020 ...

RS Americas, an industrial automation and electronics distributor, now offers variable speed drives (VSDs) for solar powered pumping applications from Schneider Electric, an automation technology ...
