Servo Motors
Servo Motors are special electric motors that are like the precise muscles of robots and automated machines. Unlike regular motors that just spin, servo motors can move to exact positions and hold there steadily. Think of them as smart motors that can turn exactly 90 degrees and stay there, rather than just spinning continuously. They're commonly used in everything from small hobby robots to large industrial machines. When you see a robotic arm picking up items in a factory or a 3D printer moving with precision, it's likely using servo motors to achieve that accurate movement.

Example Interview Questions
Senior Level Questions
Q: How would you approach troubleshooting a servo motor system that's showing positioning errors?
Expected Answer: A senior engineer should discuss systematic approach including checking power supply, control signals, mechanical alignment, and using diagnostic tools. They should mention preventive maintenance and system optimization strategies.
Q: Can you explain how you would select the right servo motor for a specific application?
Expected Answer: Should demonstrate knowledge of load calculations, speed requirements, duty cycle considerations, and environmental factors. Should also discuss cost-effectiveness and system integration aspects.
Mid Level Questions
Q: What safety considerations are important when working with servo motor systems?
Expected Answer: Should discuss emergency stops, proper guarding, power isolation procedures, and safety protocols for maintenance and programming.
Q: Explain the basic components of a servo motor system.
Expected Answer: Should describe the motor, encoder for position feedback, controller, and power supply in simple terms, explaining how they work together.
Junior Level Questions
Q: What's the difference between a regular motor and a servo motor?
Expected Answer: Should explain that servo motors provide precise position control and feedback, while regular motors simply rotate continuously without position control.
Q: What are common applications for servo motors?
Expected Answer: Should list examples like robotic arms, CNC machines, automated assembly lines, and explain basic usage scenarios.
