What is a servo motor?

The video tutorial explains how servo motors convert electrical energy into mechanical energy, focusing on their use in precise control applications like robotics and automation. It distinguishes between closed-loop and open-loop types, emphasizing the importance of torque ratings and the impact of voltage on performance. The tutorial concludes with a summary of key characteristics of servo motors.

What is a key difference between a DC motor and a servo motor?

• A DC motor can rotate in both directions, while a servo motor cannot.

• A DC motor rotates constantly when powered, while a servo motor rotates based on signals.

• A DC motor is used for precise control, while a servo motor is not.

• A DC motor is larger than a servo motor.

What is the primary advantage of a closed-loop servo motor?

• It can rotate 360 degrees.

• It provides better control over the motor's position.

• It is cheaper than an open-loop motor.

• It requires less power to operate.

How is the torque of a servo motor typically measured?

• In kilogram centimeters or oz inches.

• In volts or amperes.

• In newton meters or foot pounds.

• In watts or horsepower.

What happens to the current when a servo motor stalls?

• The current decreases.

• The current remains the same.

• The current dramatically increases.

• The current fluctuates randomly.

How does increasing the voltage affect a servo motor's performance?

• It reduces the motor's torque.

• It has no effect on the motor's performance.

• It decreases the motor's speed.

• It increases the motor's torque and speed.
