Explanation:
Starting Torque: The torque produced by a motor at the time of starting is known as starting torque. It is the minimum torque required by the motor to start rotating.
Speed Regulation: The change in the speed of the motor from no-load to full-load is known as speed regulation. It is expressed as a percentage of the full-load speed.
DC Shunt Motor: A DC shunt motor is a self-excited motor, where the field winding is connected in parallel with the armature winding. It has a relatively constant speed from no-load to full-load and has a medium starting torque.
Induction Motor: An induction motor is a type of AC motor where the stator windings are connected to the AC supply, and the rotor is either wound or squirrel cage type. It has a low starting torque and a relatively constant speed from no-load to full-load.
Differential Motor: A differential motor is a type of DC motor that has two field windings connected in series and the armature connected in parallel with the series field winding. It has a high starting torque and is used for traction purposes.
Answer: The most appropriate motor for the given requirement of medium starting torque and 15% speed regulation is a DC shunt motor. It has a medium starting torque and a relatively constant speed from no-load to full-load, which makes it suitable for applications where a constant speed is required.
