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 ...

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 ...

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 ...

This post sponsored by Texas Instruments. The TPS6040x family of devices generates an unregulated negative output voltage from an input voltage ranging from 1.6 V to 5.5 V. The devices are typically ...

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 ...

Motors account for at least half of the energy consumed in the U.S. Selecting the right control method for an application lets the motor run most efficiently while maximizing torque and overall ...

Variable speed drives (VFDs) can (and do) save energy in multiple ways. Of course, the degree of savings depends upon the application, the drive features, and how you have the drive set up. Generally, ...

High-frequency link matrix converters and inverters represent a transformative development in power electronics, combining direct AC–AC conversion with high-frequency pulse width modulation (PWM) to ...

A series of variable-frequency inverters, CFW11, features the world’s most advanced technology for three-phase ac induction motor control, according to the manufacturer. It offers efficiency ratings ...
