Q: Doesn't the rotor get shorted out (maybe a small resistance) and it starts as an induction (wound rotor) motor? Just thinking out loud - If the starting SCR (I can't read the number - but the one associated with D1) were to stick on, that would short out the exciter, which would take out (short) two SCRs, (one on each side of the bridge ...
