Synchronous Motor

[mithko]

For a synchronous motor:
1. what's the relatiship between the output power (or output torque) and the supply current?
2. does the rated current refer to the current from the power supply to the stator windings or does it refer to the field current which is actually fed into the rotor windings?

1. Not quite linear.
2. No.
