Should you specify an “inverter duty,” “inverter ready,” “inverter rated,” or a “VFD compatible” motor for your fans and pumps in HVAC applications? Is there a difference in these terms? Don’t answer ...

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 ...

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 ...

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 ...

Engineers are often unaware of the currents induced on motor shafts by variable frequency drives (VFDs) and the havoc these currents can wreak on bearings and motors; remember to use shaft grounding ...

Learn the 3 key differences between soft starters and VFDs Understand the energy and operating efficiency differences between soft starters and VFDs Find out which types of industrial applications are ...

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 ...
