A VFD controls motor speed by varying the frequency of the power supply. The basic formula to determine motor speed in revolutions per minute (RPM) is: Motor Speed (RPM) = 120 × Frequency (Hz) / Number of Poles. For example, if you have a motor with four poles and set the VFD to 60 Hz, the motor speed will be:
