my motor is sync now starting from 180v, and at 220v it draws 0.31a -
still not 0.35a - i don`t know why, maybe something is really wrong
here % )

he-he-he - i _can`t_ see anything with fluoro! you need something
that light up only at say 300v from 310v peak, coz else you would see a
full sector (or even more) instead of single mark - i`ve learned it
hard way today : ) neons ARE not much better - i used two thyratrons in
series, and they start to glow at 212v, so i have to use variac to
clearly see the mark on 1" diameter "stroboscope disk" : )

yes, you can use just anything you have - you can use start winding
as run one, you can disconnect start winding on cap/induction start
motors and so on - no problems at all.

i have a couple of questions regarding motor torque - how much is the
braking torque when you just plug motor in and it is trying to start
rotate rsg wheel? is it equal to the moment of inertia of wheel?
when a wheel is achieved the full sync speed, is braking torque drops
to zero? then we really don`t need those horse powers.
