Get Price2021-12-6u2002·u2002A variable frequency drive (VFD), also known as AC variable speed drive, AC variable frequency drive, VFD inverter or variable voltage variable frequency drive, is a type of motor controller that drives an electric motor by varying the frequency and voltage of its power supply. VFD control also has the capacity to control ramp-up and ramp-down of the motor during start …
Get Price1:40. If we multiply this ratio by maximum frequency we can determine the minimum speed which the VFD can run and still maintain control of the motor. For example, with a 60 Hz maximum frequency and 1:40 control range, a drive using the V/f control method can control a motor all the way down to 1.5 Hz.
