History & Basics
What century were servo motors first developed?
19th century
What does the feedback sensor in a servo measure?
Position (angle) of the rotor.
What advantage makes servos ideal for robotics?
High precision
What common household device uses servo motors for precise movement?
Printers
What main component is added to a DC motor to make it a servo?
Feedback mechanism (sensor & controller)
What is the shaft's job in a servo motor?
To output the motor's motion.
Which advantage allows servos to hold a joint position under load?
Stable operation
Why are servo motors in CNC machines and 3D printers?
They ensure high precision positioning
Name the 3 essential parts of a servo motor.
Motor, feedback sensor, and controller.
What role does the controller play in a servo motor?
It compares desired position with actual position and corrects errors
Why are servos more flexible than other motors in complex systems?
They can be programmed to move to specific positions and adjust dynamically
Name 2 other applications of servo motors besides robotics and CNC/Printing.
Antenna/camera gimbals, aircraft control surfaces, industrial automation etc.
