- C. Compound-wound motor
- D. Separately excited motor with armature resistance control
Why B is correct
NEETS Mod. 5 §2-2 states that a shunt motor runs at nearly constant speed from no load to full load and gives moderate starting torque, making it well suited to driving pumps, fans, and machine tools where steady speed matters.
