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 ...

AC Kinetics announced that it is “now negotiating with several drive makers who are potential licensees,” says Dr. Neil Singer, president, AC Kinetics, Inc., an advanced engineering solution provider ...

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 ...

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 ...

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 ...

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 ...

You can divide the world of electronic motor drives, which control the speed, torque, direction, and resulting horsepower of a motor, into two categories: ac and dc. An ac drive controls ac induction ...
