🔍 Key Concepts

• Brush sparking in DC motors and what causes it • The function of interpoles and commutating poles in DC machines • Whether interpoles and commutating poles are actually different names for the same component or have distinct purposes

💭 Think About

• Think about which specific type of pole is installed between the main field poles specifically to improve commutation and reduce sparking at the brushes. • Ask yourself if there is any meaningful technical difference between an "interpole" and a "commutating pole" in the context of a DC motor, or if they refer to the same thing. • Consider why brushes might need to be moved in some designs, and what feature was added to motors so that you no longer have to move the brushes to reduce sparking.

✅ Before You Answer

• Verify the definition of interpoles in a DC motor and what they do to the armature reaction and commutation. • Verify the definition of commutating poles and whether this is just another term for interpoles. • Confirm which single choice correctly reflects the standard terminology used in marine engineering references.
