A grouping of Mitsubishi Electric’s AC drives or variable frequency drives (VFDs). In the competitive landscape of machine design, engineers in food, pharmaceutical and manufacturing sectors face the ...

Adjustable or variable frequency drives — AFDs or VFDs — use rectifiers to convert ac powerline electricity into direct current. Then inductor-capacitor filters smooth its waveforms and ...

A variable frequency driven (VFD) is a type of motor that controls the levels of frequency and voltage that alter the speed of an electric motor. The drive alters torque and motor speed and can be ...

The way we control the speed of fan motors or pump motors has tremendously changed in the past two decades with the introduction of variable-frequency drives (VFDs), aka variable-frequency controllers ...

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 ...

When selecting the most efficient and cost-effective variable frequency drive (VFD), it’s essential to understand the specific considerations involved in your commercial venture. No two industrial ...

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 ...

In this episode of “EC&M Tech Talk,” Randy Barnett, a journeyman electrician, electrical instructor, inspector, author, trainer, and electrical safety expert, first briefly discusses the background of ...

When it comes to making decisions among various automation technologies to perform a task, the answer is rarely clear cut. Ultimately, the decision is often tied to the specifics of the application ...

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, ...

Medium voltage variable frequency drives (MV VFD) are high consideration, high cost assets engineers are incorporating more and more into manufacturing process. There are plenty of benefits these ...

For the past two decades, Insulated Gate Bipolar Transistors (IGBTs) and their associated silicon (Si)-based Free Wheeling Diodes (FWDs) have been the mainstay switching devices in 3-phase inverters.
