Providing Fan Motor Power Full Load Current in Ampere for three phase 460 Volts, 60 Hz Supply Power
The inputs required for this tool are Process Flowrate in SCFM, Process Temperature in Degree Fahrenheit, Fan Static Pressure in “WC, and Fan Efficiency in % Units.
This tool calculates the ACFM first by calculating the temperature correction factor and then Fan Motor Power in HP.
Using the table provided, the nearest Motor power in HP (NEMA Classification ) and relevant Motor Full Load in Ampere can be determined.
