Question 1 of 27070

In DC motor construction, where are the commutating windings wound?

🔍 Key Concepts

• Commutation in DC motors – what problem are these special windings trying to fix? • The role and physical location of interpoles (commutating poles) in a DC machine • Difference between main field poles and any smaller auxiliary poles between them

💭 Think About

• Think about which part of the motor needs help correcting sparking when the armature coils switch current direction. • Ask yourself: are commutating windings placed on the large main field poles, the rotating part, or on separate smaller poles provided just for improving commutation? • Visualize the cross‑section of a DC motor: where are the extra, narrower poles located relative to the main poles and armature?

✅ Before You Answer

• Verify which component is specifically added to improve commutation and reduce brush sparking. • Confirm whether commutating/commutation windings are stationary (on the stator) or on the rotor (armature core). • Check that you can distinguish between main poles for the main field and the auxiliary poles placed between them.
