🔍 Key Concepts

• Three-phase synchronous motor construction: rotor vs. stator roles • Difference between AC supply to stator and DC excitation to rotor in synchronous machines • Purpose of slip rings and brushes in providing excitation power to the rotor

💭 Think About

• Which part of the synchronous motor (rotor or stator) must create a rotating magnetic field that matches the three-phase power system? • Does the rotor of a synchronous motor usually need constant polarity (like a DC electromagnet) or a changing AC polarity to stay in step with the rotating field? • What kind of power source is normally used with slip rings and brushes in synchronous machines: DC excitation or AC running power?

✅ Before You Answer

• Identify which windings (rotor vs. stator) are designed for three-phase AC line power in a synchronous motor • Confirm which winding must be excited by DC to produce a steady magnetic field for synchronous operation • Eliminate any choice that gives the stator only single-phase or DC if the machine is clearly described as a three-phase synchronous motor

Assuming that a three-phase synchronous motor is separately excited, what statement is true concerning power supplies?

The rotor winding via slip rings and brushes is connected to a three-phase AC power source, and the stator winding is directly connected to a single-phase AC power source.

The rotor windings via slip rings and brushes are connected to a three-phase AC power source, and the stator winding is directly connected to a DC power source.
