What is a Servo Motor?
A servo motor is a type of rotary actuator or linear actuator that allows for precise control of angular or linear position, velocity, and acceleration. It consists of a motor coupled to a sensor for position feedback. This feedback loop allows the motor to accurately adjust its position based on a control signal. In the context of industrial sewing machines, the servo motor replaces the traditional clutch motor, offering greater control over the sewing process and significant energy savings. The core components of a servo motor typically include a DC or AC motor, a gear reduction system, a position sensor (such as an encoder or potentiometer), and a control circuit. The control circuit receives signals from the sewing machine's controller and adjusts the motor's speed and position accordingly. Servo motors are known for their high torque, low noise, and precise control, making them ideal for applications requiring accuracy and repeatability. The closed-loop feedback system ensures that the motor maintains the desired position even under varying loads, contributing to consistent and high-quality sewing.
