What is the primary function of a servo motor?
To provide linear motion
To provide accurate control of position and speed
To increase torque without feedback
To decrease electrical current
Answer explanation
Servo motors are designed for precise control of angular or linear position, velocity, and acceleration. This is why they are commonly used in applications requiring high accuracy

What type of feedback is commonly used in a servo motor system?
Voltage feedback
Current feedback
Position feedback
Temperature feedback
Answer explanation
Position feedback, typically provided by encoders or potentiometers, is crucial for servo motor systems to continuously monitor and adjust the motor's position for accuracy

Which of the following is an essential component of a servo motor?
Brake
Potentiometer
Encoder
Diode
Answer explanation
Encoders provide the feedback required for position control, making them a key component in servo systems. Potentiometers are also used in some systems, especially for simpler feedback

What does a servo motor's control signal determine?
Voltage
Speed and direction
Position, speed, and torque
Current
Answer explanation
The control signal, typically using PWM, helps regulate the motor's position, speed, and sometimes torque, depending on the requirements of the system.

What type of motor is typically used in a servo motor system?
Stepper motor
DC / AC motor
Induction motor
Synchronous motor
Answer explanation
DC motors are commonly used in servo systems because they respond quickly to control signals and are easier to manage for precise control. AC motors are also used in industrial servo applications

MULTIPLE CHOICE QUESTION
20 sec • 10 pts
How does a pulse-width modulation (PWM) signal affect a servo motor?
It controls the temperature
It controls the torque output
It controls the motor's rotational position
It stabilizes the motor's speed
Answer explanation
The PWM signal varies the duty cycle, which in turn adjusts the motor's rotational position, making it a common method for controlling servos in precise applications.
