It's amazing. And then what is the function of these windings? This is a diagram of the engine of a Marconi gramophone, but a different model than mine ...
Here, not even three, but four windings and two starting windings are switched on through the phase shift capacitor. Have I misunderstood their function?
PS. And by the way, this engine has a centrifugal mechanical speed regulator. I have seen this only on old pre-war electrogramophones
