🔍 Key Concepts

• Basic purpose of an electric motor in a ship’s system • Difference between a motor and a generator • Relationship between electrical energy, magnetic fields, and mechanical motion

💭 Think About

• Ask yourself: What does a motor actually DO on board? Does it move something mechanically, or just change electrical characteristics? • Which of these options sounds like a cause used inside the motor, and which sounds like the main job/output of the motor? • Think about practical examples: winches, pumps, and fans driven by electric motors—what are they providing to turn those pieces of machinery?

✅ Before You Answer

• Identify which choice describes mechanical output rather than an internal side-effect. • Eliminate any options that sound more like what a generator or transformer does. • Check which answer matches what you would measure at the motor shaft (what it delivers) rather than what’s happening inside the windings.
