Solution

Analyze the Question

  1. Understand the Concept: The question pertains to the use of DC (Direct Current) and AC (Alternating Current) machines as servo motors. Servo motors are typically used in applications that require precise control of angular or linear position, velocity, and acceleration.

Evaluate the Options

  1. DC Machines: DC motors are often used as servo motors due to their ability to be easily controlled. They can provide good torque at low speeds, which is beneficial for positioning applications.

  2. AC Machines: AC motors, specifically synchronous and asynchronous (induction) motors, can also be used as servo motors. However, they usually require additional control mechanisms, like variable frequency drives (VFDs), for precise control.

Conclusion

Both types of machines can function as servo motors, hence the correct choice is:

Final Answer

b. True
