Wasn't the Scott three-phase transformer invented by Westinghouse
engineer Charles F. Scott in the late 1890s to bypass Thomas Edison's
more expensive rotary converter and thereby permit two-phase generator
plants to drive Nikola Tesla's three-phase motors? And it is self
balancing the load.
I think that would work better than en electronics or microcontroller
based solution.

I'm trying to find a 120v 1200rpm synchronous motor to spin my 6
electrode rotating spark gap. I have a 1200 rpm synchronous motor but
it's 3-phase and 230volts. I have been looking into microcontroller
solutions and building my own 3-phase motor driver. I have a vfd that
can spin the motor at the proper rpm but the phase drifts slowly around
the clock as seen by my homemade 120hz led strobe light.. Existing vfd's
don't have inputs for zero crossing signals and so can't be phase locked
to the line. If anyone knows where I can find a motor or even if they
exist please let me know. Thanks in advance!
