🔍 Key Concepts

• Field windings vs. armature windings in an alternator • Difference between AC excitation and DC excitation • How changing the strength of the magnetic field affects output voltage

💭 Think About

• In a typical shipboard three-phase alternator, which part is rotating and which part is stationary? Field or armature? • Which is easier and safer to control: high-current three-phase output, or a smaller control current to the magnetic field? • When you want to raise or lower the alternator’s output voltage, what exactly are you adjusting inside the machine?

✅ Before You Answer

• Identify whether the field windings are supplied with AC or DC in standard marine alternators • Confirm which winding (field or armature) actually carries the three-phase output delivered to the ship’s bus • Verify that voltage regulation is done by varying the excitation current, not by directly switching the main three-phase output
