Deciding where to put your drives requires more than just casual consideration. If your VFDs are failing prematurely, it may be because they're located in your motor control centers (MCCs). MCCs ...

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 ...

Homeowners rely on a continuous flow of water to do daily household activities like watering the lawn, laundry, running the dishwasher and giving the kids a bath. Often, these activities take place at ...

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

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 ...

A VFD reports a low-volts fault when the drive's dc link voltage drops below 62% of the nominal level for the high setting (480 Vac) and 50% of nominal for the low setting (400 Vac). The +10% and -15% ...

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 ...

The experts at eMotors Direct outline how VFD’s can damage bearings and discuss preventative measures to prevent VFD induced bearing damage Electric motors fitted with VFDs (Variable Frequency Drives) ...

Electric motors fitted with variable frequency drives are at risk of bearing damage due to a build-up of current in the rotor that discharges through the shaft, damaging the lubrication and bearing ...
