Oh that's a good question- they need to be in the same phase or else they will fight each other. The motor would just hum or maybe
turn slowly but it wouldn't run properly
It's kinda hard to explain but they both need to be riding on the same side of the ac waveform. The ac is going plus and minus 60 times
per second and if one winding is going plus while the other is going minus then they cancel each other out- see?
It's like shorting the output of a transformer- in this case the motor would be trying to turn in both directions at once, that was the
reason for doing the two run tests in post #27- they need to be in phase and ready to turn the motor in the same direction when
the start winding says "go"
That Nikola Tesla was one smart guy- makes Edison look like a schoolboy
