Final answer:
The DC motor with excellent starting torque and stability under no load condition is the compound motor. Compound motors combine the features of shunt and series motors, which allows them to have both high starting torque and stable speed regulation.
Step-by-step explanation:
The DC motor that has excellent starting torque and will not run away under no load condition is the compound motor (D). A compound motor combines the features of both shunt and series wound DC motors, wherein it includes both a shunt (parallel) winding and a series (sequential) winding on the armature. This dual winding allows it to have high starting torque due to the series winding while also maintaining a stable speed under varying load conditions thanks to the shunt winding.
Other types of motors like the shunt motor (A) have good speed regulation but lower starting torque compared to a compound motor. The series motor (C) has high starting torque, but its speed can run away if it is not under load. A squirrel cage motor (B) is not a type of DC motor but rather an induction motor that operates on alternating current (AC).
