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 ...

Single- and three-phase alternating current (AC) motor speed can be controlled by controlling the frequency of the voltage coming to it. Motor speed has a lot to do with the capacity of refrigeration ...

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 ...

When applied to blowers and pumps, variable-frequency drives (VFDs) offer energy savings. In mechanical applications, they allow fine adjustments that wouldn't be possible by other methods. Despite ...

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 ...

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 ...

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 ...

A recent trend in nuclear power plant upgrades has been the replacement of the motor-generator (MG) sets that drive the reactor circulating pumps with variable-frequency drives (VFD). Siemens’ first ...

It is interesting to look at figures from the Energy Information Administration about where energy gets consumed in our economy. These figures reveal that industrial uses account for 31% of all energy ...
