Closed-loop servo motor refers to an encoder structure that can feedback the motion state of the motor to form a closed-loop control.
Specifically, when the servo motor is running, it will output the corresponding position, speed and torque according to the control instructions; At the same time, the motion state of the motor will also return to the controller through the feedback device, forming a closed-loop control.
This closed-loop control can ensure that the motor moves strictly according to the instructions of the controller, thereby improving positioning accuracy and operating efficiency.
