1. A servo mechanism is used to adjust the position and orientation of an object

An automatic control system where the output controlled variable can follow any changes in the input target (or given value). Servo mainly relies on pulses for positioning. Basically, it can be understood as follows: when a servo motor receives one pulse, it will rotate the corresponding angle of one pulse to achieve displacement. Because servo motors have the function of emitting pulses, they will emit a corresponding number of pulses every time they rotate an angle. This forms a response or closed loop with the pulses received by the servo motor. In this way, the system will know how many pulses have been sent to the servo motor and how many pulses have been received back. In this way, the rotation of the motor can be accurately controlled to achieve precise positioning, which can reach 0.001mm. DC servo motors are divided into brushed and brushless motors. Brushed motors have low cost, simple structure, large starting torque, wide speed range, easy control, and require maintenance. However, maintenance is inconvenient (such as replacing carbon brushes) and generates electromagnetic interference, which has environmental requirements. Therefore, it can be used in cost sensitive general industrial and civilian applications.

Brushless motors have small size, light weight, high output, fast response, high speed, low inertia, smooth rotation, and stable torque. The control is complex and easy to achieve intelligence. Its electronic commutation method is flexible and can be square wave commutation or sine wave commutation. The motor is maintenance free, highly efficient, operates at low temperatures, emits minimal electromagnetic radiation, has a long lifespan, and can be used in various environments.

2. AC servo motors are also brushless motors, divided into synchronous and asynchronous motors. Currently, synchronous motors are generally used in motion control, which have a large power range and can achieve high power. Large inertia, maximum high rotational speed, and rapid decrease with increasing power. Therefore, it is suitable for applications that operate smoothly at low speeds.

3. The rotor inside the servo motor is a permanent magnet, and the U/V/W three-phase electricity controlled by the driver forms an electromagnetic field. The rotor rotates under the action of this magnetic field. At the same time, the encoder provided by the motor feeds back the signal to the driver, and the driver compares the feedback value with the target value to adjust the angle of rotor rotation. The accuracy of servo motors depends on the accuracy (number of lines) of the encoder.
