Servo driver is a kind of controller used to control motor motion, which can realize the extremely precise control of motor motion. It plays an important role in automation applications, such as industrial automation, robotics, aerospace, medical equipment, automatic vehicles and other fields.
Servo drivers work by converting input signals into signals that control motor motion. In the servo system, the driver receives the control signal from the controller and guides the current to the motor through the current amplifier, thus realizing the purpose of controlling the motor rotation. The driver can also monitor the running state of the motor and provide feedback signals to the controller so that the controller can adjust the output signals in time to maintain the accuracy and stability of the motor operation.
Servo driver is composed of control circuit, power circuit and feedback circuit.
Control circuit:
The control circuit is the core part of servo driver, which is composed of microprocessor and controller. The control circuit receives the command signal from the servo controller and converts it into the control signal of the driver power circuit, which controls the movement of the servo motor and the action of the peripheral equipment.
Power circuit:
Power circuit is an important part of the servo driver, it controls the output current and output voltage through the power tube and other components, so that the servo motor according to the requirements of speed and steering control.
Feedback circuit:
The feedback circuit is used to detect the output position of the servo motor and feed the detected real-time position information back to the control circuit to achieve a more accurate control effect. The feedback circuit mainly includes encoder, Hall element and sensor.
