🔍 Key Concepts

• Difference between armature and field in an AC generator • Practical reasons for keeping high-current windings stationary on large shipboard generators • Typical construction of synchronous AC ship service generators (which part usually rotates?)

💭 Think About

• On a large ship, which is easier and safer: collecting high current from a moving part, or from a fixed part? How does that affect whether the armature should rotate or be stationary? • Which winding (field or armature) usually carries less current and is therefore more practical to place on the rotating part? • Think about how three‑phase power is taken off a generator: from a rotating coil through slip rings/brushes, or from stationary windings directly into cables?

✅ Before You Answer

• Identify which component (armature vs field) normally carries higher current in a ship service AC generator. • Decide which component is more practical to make the rotating part, considering mechanical wear and brush/slip‑ring issues. • Eliminate any choice that suggests an oscillatory motion if you know most ship generators rotate continuously rather than oscillate.
