Variable-frequency drives (vfd’s) go by a number of different names, such as variable-speed drives, adjustable-speed drives, and adjustable-frequency controllers. It doesn’t really matter what you ...

Increasingly common, variable frequency drives (VFDs) are used to control motor speed elevating the frequency of power pulses/sec fed to motors for faster Increasingly common, variable frequency ...

For retrofits Electro Static Technology’s AEGIS® Shaft Voltage Test Kit makes it easier than ever to measure and document damaging VFD-induced voltages while there is still time to head off bearing ...

A typical low-voltage variable-frequency drive. Industrial facilities commonly use variable-frequency drives (VFDs) to control the speed at which alternating current motors operate. Let’s examine a ...

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 ...

Targeting ac-motor-drive applications, the symmetrical VFD (varying-frequency-drive) cables carry power from industrial ac-drive systems to ac motors. A dual-copper-tape shielding provides a ...

Jim Alt explains Nord Gear's new IE5 motor and variable frequency drive. These IE5 motors operate at high efficiency even at reduced speeds and with reduced loads. In this video, Alt explains the ...

In this episode, we connect with Steve Wetzel, a member of IEEE and principal applications engineer with Southwire Company, one of North America's largest wire and cable manufacturers and the sponsor ...

You recently hired on as the Plant Electrical Maintenance Supervisor. The job was created because of a list of problems that have remained unsolved despite the best efforts of the eleven maintenance ...
