Know the Speed/Power/Torque Trade-Off for Your Application
Did you know that when you control and vary the operating speed of your industrial centrifugal fan or blower using a variable frequency drive (VFD), you’re affecting both horsepower (HP) and torque? It’s not always obvious, but it’s important to understand when you may be operating at reduced power or torque due to changes in speed because you always need a certain horsepower to drive the fan and move air through the type of pressure in your system.
