1080-00126

Motor drive: After the servo motor receives the current signal output by the driver, the electromagnetic field

inside the motor changes, thereby driving the motor shaft to rotate. This rotation is achieved through electromagnetic

interaction, that is, the magnetic field generated by the current in the motor winding interacts with the motor permanent magnet or external magnetic field.

1080-00126 Feedback systems: Servo motors are usually equipped with feedback systems, such as encoders or

sensors, to measure the actual position and speed of the motor. This feedback is sent back to the drive or controller for comparison with the desired position and speed.

Closed-loop control: By comparing the actual position and speed with the desired position and speed, the driver

or controller can calculate the error and adjust the current signal to reduce the error. This closed-loop control

method enables the servo motor to accurately track the control signal and realize high-precision position control and speed control.

1080-00126 Dynamic adjustment: During the operation of the motor, the drive will be dynamically adjusted

according to the feedback information to cope with load changes, mechanical disturbances and other external factors to maintain the stability and accuracy of the motor movement.

In short, the working principle of servo motor drive is to drive the motor to rotate by precisely controlling the current

signal, and use the feedback system to achieve closed-loop control to achieve the purpose of high-precision position, speed and acceleration control.
