🔍 Key Concepts

• Shunt-wound DC motor connection: field winding in parallel (shunt) with the armature • How armature current and field current change as load increases • Meaning of speed regulation in DC motors (change in speed from no-load to full-load)

💭 Think About

• Think about what happens to the field flux in a shunt motor when the load on the shaft increases: does it change a lot or stay nearly the same? • If the motor’s speed is mainly determined by applied voltage and field flux, how will the speed change when load increases? • Compare the typical properties of series-wound vs shunt-wound DC motors in terms of starting torque and speed behavior.

✅ Before You Answer

• Be clear on the definition of good vs poor speed regulation (small vs large speed change with load). • Check which type of DC motor is known for high starting torque (series, shunt, or compound). • Verify how a shunt field being in parallel with the supply affects current and speed when load varies.
