NOT KNOWN FACTUAL STATEMENTS ABOUT VFD PANEL

But, if we lessen the frequency to 30Hz, then we must also lessen the voltage to 240V as a way to keep the V/Hz ratio. How are we likely to reduce the voltage if the only voltage We now have is 650VDC?The result is inefficiency, with many squandered materials and energy. Motor’s speed should really match precisely what is needed by the process. W
