So, I ran into a motor and transformer someone was trying to get started today.
Motor = 1HP,
Transformer = 750VA
With the transformer tapped from the line, the motor won't start. With the transformer removed, it starts perfect.
I suspect the transformer is too big. The motor has ~30 ohm at each leg and the transformer is only about 8 ohms. So when it is tapped, two legs are only reading an 8 ohm resistance.
Am I in the wrong here? I suppose it could be something else and the way it is wired.
(note - it is only a motor and transformer, nothing else on the 'machine')
