A Variable Frequency Drive (VFD) regulates the speed of a 3-phase AC electric motor by controlling the frequency and voltage of the power it delivers to the motor. These devices, also known as ...

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 ...

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 ...

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 ...

There are well-known benefits of using variable-frequency drives (VFDs) to reduce energy consumed by induction motors. Federal, state and local agencies in the U.S. now all give incentives for ...

Variable-frequency drive (VFD) control panels, the Endura™ line, has been introduced. The Endura PB (Pressure Booster) Control Panel is designed for commercial pressure booster applications using ...

It shows the vector motor control and one the of best sensorless vector control frequency inverters. Vector control is one of the most popular electrical motor control modes in electric industry that ...

The new Cat ® VFD-A800/W800 Variable Frequency Drive for longwall systems is designed to work in conjunction with Cat UEL and Cat CST gearboxes to deliver variable speed of the armored face conveyor, ...

Honeywell and Danfoss are partnering to integrate variable frequency drive (VFD) technology with Honeywell's Experion Process Knowledge System platform to streamline motor control, reduce energy ...

Single-phase and 3-phase AC squirrel cage induction motors need some type of control circuit to initiate a start or stop function. The two types of ladder control circuits commonly used are the 2-wire ...
