SCFM refers to "standard cubic feet per minute" or the given flow rate of air at standard room temperature and pressure. Standard air flow is the baseline required flow; depending on your operating conditions (i.e. differing pressure and temperature) this tool allows you to convert the required SCFM, to the actual flow or ACFM that you will read from your instruments.

Motor Horsepower Torque Versus VFD Frequency

Apr 26, 2013When the speed of an AC motor is controlled by a VFD, HP or torque will change depending on the change in frequency. Figure 1 provides a graphical illustration of these changes. The X axis is motor speed from 0 to 120 hertz. The Y axis is the percent of HP and torque. At 60 hertz (base motor speed), both HP and torque are at 100 percent.
