Definition of servo motion

Photonics Dictionary

servo motion: Servo motion is the controlled motion of a mechanical system achieved through the use of a servo motor, which utilizes feedback mechanisms to ensure accurate positioning, speed, and acceleration. This type of motion is commonly used in applications where precise control is essential.

Servo motor: A motor equipped with a feedback system (such as encoders or resolvers) that provides information about the position, speed, and direction of the motor shaft.

Feedback control: A closed-loop control system where the actual position or speed of the motor is continuously monitored and compared to the desired setpoint. Adjustments are made in real-time to minimize the error between the actual and desired values.

Controller: The control unit or drive that processes feedback signals and sends commands to the servo motor to achieve the desired motion. It typically implements control algorithms such as PID (Proportional-Integral-Derivative) control.

Applications: Servo motion is widely used in robotics, CNC machinery, automated manufacturing, aerospace, and other fields requiring precise and dynamic control of mechanical components.

Characteristics of servo motion include:

Precision: High accuracy in achieving and maintaining the desired position, speed, and acceleration.

Responsiveness: Rapid response to changes in control signals, allowing for quick adjustments and fine-tuning.

Versatility: Ability to handle complex motion profiles and operate in various modes, including position control, speed control, and torque control.

Servo motion systems are essential in applications that demand high performance and precision, enabling efficient and accurate control of mechanical processes and devices.
