Introduction
Servo motors are essential in modern industrial automation, robotics, and CNC machinery, enabling precise control over position, velocity, and acceleration. Their ability to provide accurate and efficient movement makes them indispensable in various industries.
What is a Servo Motor?
A servo motor is a rotary actuator designed to precisely control angular or linear position, velocity, and acceleration. It consists of:
- A motor (AC or DC) – Provides rotational force
- A feedback sensor (encoder or resolver) – Measures position and speed
- A controller (servo drive) – Regulates movement based on feedback
Types of Servo Motors
1. AC Servo Motors
- High efficiency and power density
- Ideal for industrial automation and CNC machines
- Smooth and stable operation with precise torque control
2. DC Servo Motors
- Cost-effective and simple control system
- Suitable for small-scale robotics and consumer electronics
- Fast response time but requires regular maintenance
Key Benefits of Servo Motors
✅ Precision and Accuracy – Delivers high positional accuracy in automation systems.
✅ Energy Efficiency – Consumes power based on demand, reducing energy costs.
✅ High Torque at Low Speeds – Maintains efficiency in heavy-load applications.
✅ Smooth and Quiet Operation – Minimizes vibrations and noise in precision tasks.
Applications of Servo Motors
