Q

As load is added to a DC shunt motor, how will the motor respond?

🔍 Key Concepts

• Speed-load characteristics of a DC shunt motor • How armature current and torque change as load increases • Effect of shunt field connection (parallel to supply) on speed regulation

💭 Think About

• When you add mechanical load, what must happen to motor torque to carry that load, and how is torque related to armature current in a DC motor? • If the field winding is connected in shunt (parallel) to the supply, does the field flux change much when load changes? How does nearly constant flux affect speed? • Think about industrial uses of DC shunt motors: are they chosen for applications needing nearly constant speed, or for large speed variations with load?

✅ Before You Answer

• Verify the typical speed–torque curve for a DC shunt motor (how steep or flat it is). • Confirm that field current in a shunt motor stays almost constant with load (because it is tied across the supply). • Check whether speed changes are described as large, none, or small/limited when load is applied to a DC shunt motor.
