A servo motor is an electric motor capable of precisely controlling position, speed, and acceleration, and it usually consists of the following components:
Motor: The core component of the servo motor, usually using a brushless DC motor or an AC synchronous motor.
Reducer: A device that converts the output of a high-speed motor into a low-speed high-torque output, which can improve the torque, accuracy and stability of the system.
Encoder: A device that measures rotational angle or linear position changes and provides feedback signals to the controller for closed-loop control.
Controller: It is the brain of the servo motor, which can receive the encoder feedback signal and control the movement of the motor according to the set position, speed and acceleration and other parameters.
