The new generation of CFW11 variable-frequency inverters feature Vectrue technology, which combines V/F, Sensorless Vector, VVW, and vector (with encoder) control techniques all in one product. The ...

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 ...

Adjustable speed drives (ASDs) or variable speed drives (VSDs), also called variable frequency drives (VFDs), typically control a motor's velocity or torque output. Most adjustable frequency drives ...

Nord Drivesystems has been developing drive electronics for more than 30 years and is one of the pioneers of innovative inverter technology. With their family of NORDAC variable frequency drives (VFDs ...

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 ...
