Consider the following statements related to A.C. servomotors compared...
An A.C. servomotor doesn’t require brushes compared to a D.C. servomotor. So, it gives maintenance free operation. It’s efficiency is less due to low power output but, gives smooth operation.

Consider the following statements related to A.C. servomotors compared...
AC servomotors are widely used in control system applications due to their various advantages over DC servomotors. Let's analyze the given statements to determine which ones are true regarding AC servomotors.
1. It has less efficiency.
This statement is false. AC servomotors are known for their high efficiency. They have a higher power factor and lower losses compared to DC servomotors, resulting in better overall efficiency.
2. It is maintenance-free.
This statement is false. AC servomotors, like any other motor, require regular maintenance. They may need lubrication, cleaning, and occasional parts replacement to ensure optimal performance and longevity.
3. It gives smooth operation.
This statement is true. AC servomotors provide smooth and precise operation due to their continuous and sinusoidal nature of the AC power supply. They can achieve a high degree of accuracy and control in controlling speed, position, and torque.
4. It gives high power output.
This statement is true. AC servomotors are capable of providing high power output. They can generate high torque at low speeds, allowing them to handle heavy loads effectively. AC servomotors are often used in applications that require high power and dynamic response.
Based on the analysis, the true statements regarding an AC servomotor are:
- It gives smooth operation.
- It gives high power output.
Therefore, the correct answer is option 'C' - 1, 2, and 3.
