🔍 Key Concepts

• Cumulative compound-wound DC motor: how the series and shunt fields are arranged relative to the armature • Difference between short-shunt and long-shunt connections • What “in parallel” and “in series” mean in a compound motor field circuit

💭 Think About

• Sketch a simple DC motor with armature, series field, and shunt field. For a short-shunt connection, decide which part(s) of the circuit the shunt field is directly across. • Compare how current flows through the series field versus the shunt field. Which winding should carry full armature current, and which winding should be across the supply? • Ask yourself: in a short-shunt cumulatively compounded motor, is the shunt field connected only across the armature, or across both the armature plus series field together?

✅ Before You Answer

• Be clear on the definition of short-shunt vs long-shunt in compound motors before choosing. • Verify whether the shunt field is connected directly across the supply or only across the armature terminals. • Confirm which elements (armature, series field) are in series and which are in parallel in a cumulative compound-wound configuration.
