If we wish to lessen the motor frequency to 30 Hz, then we only swap the inverter output transistors extra slowly and gradually. But, if we reduce the frequency to 30Hz, then we must also lessen the voltage to 240V to be able to preserve the V/Hz ratio (see the VFD Motor Theory presentation For additional on this). How are we gonna reduce the voltage if the sole voltage We have now is 650VDC?
Furthermore, VFDs may also help to lessen the amount of dress in and tear within the mechanical elements with the pump, which can enable to lower maintenance prices and downtime.
