This is a weird little scrap yard find that has been in my orphan collection.It suggests what we are discussing, except we are talking generators.Cheers Warren

Hi Warren
With AC motors usually you need to spin the motor to a specific rpm so it will latch up witb tbe A C sinewave using an external "pony" motor to do tbis...tben disconne the pony motor afterwards. Exampke 4 pole AC motor with 60bz sinewave needs to be going 1800rpm. Of course different with rotovertor since it can start from stop using start caps.
So to make tbe motor in Hectors drawings loop, in or order to spin by itself, the "sweetspot" in frequency of self resonance (whatever ypu call it) needs to be also a specific frequenxy of rotation too. Maybe octaves or harmonic 5ths will be strong emough...
I think the sweet spot in frrquency for less draw and mucb more power has similar effects asThane Karl Heinz delayed lenz effect where according to Woopys tests a few years ago with a 16 mag ns rotor and 36 ohm coil needs 2100 to 2300 rpm to get it to speed up umder load...so 2 pole rotor needs maybe 16 to 17k rpm range this why hopng octaves can work tpo so drop it down x12 or x24 less?
