đ 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)
đ 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 motorâs 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.
