Answer: D
Share your understanding of this question with the correct explanation.
DC shunt motors are suitable for all of the above applications: centrifugal pumps, lathes, and blowers and fans.
DC shunt motors are versatile and widely used in various industrial and commercial applications. They offer a number of advantages, including good speed regulation, relatively constant speed throughout the load range, and the ability to handle varying torque demands.
Centrifugal pumps, which are used for fluid transfer and pumping applications, can be driven effectively by DC shunt motors. The speed regulation and torque characteristics of shunt motors make them suitable for maintaining consistent flow rates in centrifugal pumps.
Lathes, which are machine tools used for turning, cutting, and shaping operations on various materials, can also be powered by DC shunt motors. The precise speed control and good torque characteristics of shunt motors allow for accurate and controlled machining processes.
Blowers and fans, which are used for air circulation, ventilation, and cooling purposes, can be effectively driven by DC shunt motors. The ability of shunt motors to maintain a relatively constant speed under varying load conditions makes them suitable for maintaining desired airflows in blowers and fans.
Therefore, the correct answer is D: All of the above. DC shunt motors are suitable for centrifugal pumps, lathes, blowers, and fans in various applications.
