Servo motor working principle

Working principle: 1. Receive signal; 2. Signal processing; 3. Convert energy; 4. Drive motor; 5. Feedback system.

The working principle of the servo motor mainly includes the following steps:

1. Receive signals: The servo motor receives signals from the control The control signal of the system or main control system, which is usually a pulse or analog signal.

2. Signal processing: After the electronic components inside the servo motor receive the control signal, they will perform corresponding processing according to the control signal. If the control signal is a pulse signal, the servo motor will determine the rotation angle or speed of the motor based on the number and frequency of pulses received. If the control signal is an analog signal, the servo motor will adjust the output torque or torque of the motor according to the voltage or current value of the analog signal, thereby controlling the rotation speed and direction of the motor.

3. Conversion of energy: After the electronic components inside the servo motor process the control signal, they convert the control signal into a corresponding electrical signal and transmit the electrical signal to the motor driver.

4. Drive motor: After receiving the electrical signal, the servo motor driver will drive the motor to rotate according to the instructions of the electrical signal. Servo motor drivers usually use power electronic devices and high-performance integrated circuits to quickly and accurately control the motor's speed and direction.

5. Feedback system: Servo motors are usually equipped with feedback devices such as encoders or tachometers. These devices can monitor the speed and position of the motor in real time and feed back the monitoring results to the control system. or master control system. The control system or main control system makes corresponding adjustments based on the feedback results to ensure that the motor can respond accurately and quickly to changes in control signals.

Through the above working principles, servo motors can achieve high-precision, high-speed, and high-response control, and are widely used in various automation equipment and industrial robots.
