Question 6A324

A shunt-wound DC motor connects its field winding in parallel (shunt) with the armature winding. This parallel connection means the voltage across the field winding is relatively constant, resulting in a nearly constant field current and, consequently, a constant magnetic field strength. Since motor speed is inversely proportional to the magnetic field strength, a stable field allows the motor to maintain a practically constant speed even when the mechanical load varies significantly. This excellent speed regulation makes option A correct. Option B is incorrect because shunt motors are known for their *good* speed regulation, not poor. Option C is incorrect; shunt motors typically have moderate starting torque, unlike series-wound motors which are known for high starting torque. Since A is correct, option D is also incorrect.
