🔍 Key Concepts

• Basic construction and operation of a DC propulsion motor • Effect of field polarity vs armature current direction on rotation • Role of interpoles in a DC motor and what they primarily correct

💭 Think About

• Think about what actually determines the direction of rotation of a DC motor’s armature: which part’s polarity or current direction has to change? • Consider whether you could practically and safely change the rotation of a large diesel engine every time you want to go astern. • Ask yourself what interpoles are designed to do in a DC motor and whether they are normally used to control direction of rotation.

✅ Before You Answer

• Verify which component in a DC motor is normally altered to change rotation direction in propulsion service. • Confirm the primary function of interpoles (are they for commutation correction or direction control?). • Consider operational practicality: which option would allow rapid and frequent reversals of propeller direction in a ship?
