🔍 Key Concepts

• Relationship between armature, series field, and shunt field windings in different DC motor types • How a compound-wound DC motor combines both series and shunt field characteristics • Why a permanent magnet DC motor schematic will NOT show field coils

💭 Think About

• In figure B, trace the current path from the positive line to the negative line. Which windings are clearly in series with the armature? • Is there any field winding that is connected directly across the supply (in parallel with the armature), and what type of field is that? • Compare figure B with a pure series-wound and a pure shunt-wound diagram: how many separate field windings do you see, and how are they connected?

✅ Before You Answer

• Verify whether the top field winding in B is connected directly across the line (a key sign of a shunt field). • Verify if the S1–S2 winding is in series with the armature path from A1 to A2 (a key sign of a series field). • Confirm that the diagram shows field coils, so it cannot represent a permanent magnet motor.
