Servo Motor: Definition and Overview
- Servo motors are electric motors that achieve precise control of position, speed, and torque via a feedback loop system.
- The term "servo" relates to its historical role as an auxiliary driver, emphasizing its high performance in modern applications.
Components of Servo Motors
- Motor: Can be AC or DC, providing mechanical power for motion.
- Sensor: Types include potentiometers and encoders; they provide feedback on position, speed, or torque.
- Controller: Compares feedback signals with desired setpoints; uses control algorithms (e.g., PID control) for precision.
Working Principle
- The controller receives a setpoint signal (the desired output) and a feedback signal (the actual output).
- An error signal is generated, indicating the difference, and the control algorithm determines the necessary adjustments to motor input.
- This process continues until the output matches the desired setpoint.
Types of Servo Motors
- AC Servo Motors: Operate on alternating current, categorized into synchronous (more efficient with precise control) and asynchronous (simpler and more rugged).
- DC Servo Motors: Use direct current and include brushed (lower efficiency and lifespan) and brushless (more efficient and durable) designs.
- Linear Servo Motors: Produce linear motion with series including iron-core (high force density) and ironless (low cogging force) types for applications demanding high precision.
Control Mechanisms
- Servo motors can be controlled using analog signals (continuous) or digital signals (discrete), depending on the application.
- Common control algorithms include:
- PID Control: Adjusts control signals based on the proportional, integral, and derivative aspects of the error signal.
Applications
- Widely used in fields that require high-precision movement such as robotics, CNC machinery, and automated manufacturing processes.
- Also utilized in medical equipment and semiconductor manufacturing for their responsiveness and fluid motion capabilities.
