Why would you run a static inverter to make one frequency of AC then use a
MG set to convert to another frequency? Seems like a real kludge to me,
not to mention, a very noisy setup.
You must not have been torturing with the correct motors. A series wound
AC-DC motor with its brushes is much nastier than flourescent or HID
lighting. "You do know that, do you not?" Try it, but watch the exploding
MOVs and FETs!
