can i turn a ac motor into a dc with some kind of chip to increase the hz?
You can speed up an AC motor by increasing frequency, but you cannot run (most) AC motors on DC. Their supply MUST be AC. There is just 1 small exception, the so- called universal AC/DC motors often found on such things as sewing machines.
with an invertor or some sort of driver you proberlly could. most of the variable speed drives i work on turn ac into dc the pluse it back to create an AC sin wave.Lots of small motors i see in air-conditioners these days seam to be dc steppers
Once you've converted to DC, Hz is no longer a measurement. You should really study some basic electronics books.
