The correct answer is: C. Cumulative compound motor<\/strong><\/p>\n A cumulative compound motor is a type of DC motor that has both series and shunt windings. The series winding is connected in series with the armature, while the shunt winding is connected in parallel with the armature. The combination of these two windings gives the cumulative compound motor a number of advantages over other types of DC motors.<\/p>\n One advantage of the cumulative compound motor is that it has a high starting torque. This makes it ideal for use in applications where a large amount of torque is required at startup, such as machine tools.<\/p>\n Another advantage of the cumulative compound motor is that it has a good speed regulation. This means that the speed of the motor remains relatively constant even under load changes. This is important in applications where a constant speed is required, such as in machine tools.<\/p>\n Finally, the cumulative compound motor is relatively efficient. This means that it uses less power than other types of DC motors, which can save money on energy costs.<\/p>\n The other options are incorrect because:<\/p>\n [amp_mcq option1=”Series motor” option2=”Shunt motor” option3=”motor will be preferred for machine tools?
