Yes, I realize from reading here. But I have never done that. I wonder how
"ideally shaped" the sine-wave is? I assume the three phases would be
precisely 120° apart? Wonder if a quill-motor like this designed for "up to 400
Hz" was operated on 560 or 600 Hz or more if the magic smoke would not depart
very rapidly? Somebody that KNOWS about this TELL us!
