I know this is anecdotal "evidence," but I have run my Iwaki through my UPS (which uses a modified sine-wave as its output when running on batteries) once and it hated it. I only ran it for a couple of minutes, but that was enough for me to never want to do it again. There was considerably more noise produced by the motor, and the poor thing ran a lot hotter than it usually does.
