Re: (ET) rotary inverter specifics

Or is it the surge?  Someone said that the waveform on the rotary
inverters was pretty good.

The wave form of the output product. Any deviation from the relatively
pure 
sine wave AC that these devices were designed for will result in
certain, 
violent death for them.{Especially if the RMS voltage ends up being
higher, 
because the waveform is closer to 'square'.}
AC motors with brushes in them, {the so called "universal" motor},
don't 
care about that, and that is the same with any kind of resistance
heater, so 
long as it does not contain a fan.
