Infinite current draw for BLDC/Synchronous AC motor
You need to first study basic circuit theory more carefully. You also need to understand more about motors.
The rotor of the motor connected in series with the stator is what controlled the current as the motor was used originally. The rotor had resistance, but more importantly, the rotor generated a voltage called &quot;back electromotive force (EMF). that opposed the current.
120 volts is way too much voltage to apply to just the stator. You could connect resistance in series to reduce the current, but that will generate quite a bit of heat and waste energy. It would be better reduce the voltage with a transformer. You need an AC ammeter to measure the current with whatever you can find to connect in series temporarily. You could start with incandescent lightbulbs, but just one will probably limit the current too much. You probably need several lightbulbs connected in a parallel group with the group connected in series with the motor.
Also, with your 4-pole rotor, only two poles will be effectively engaged with the two-pole stator.
If I wanted to do something like this, I would use the stator of a shaded-pole fan motor with a 2-pole rotor. A stator like that would not need anything to reduce the current.
