Best answer

Servo systems can be classified into the following three categories according to the driving elements:

1. DC servo system:

- Definition: DC servo system uses DC motor as driving element.

- Features: It has the advantages of fast response speed, large torque and relatively low cost.

- Application field: It is suitable for applications that require high-speed and high-performance control, such as CNC machine tools, aircraft, etc.

2. AC servo system:

- Definition: AC servo system uses AC motor as driving element.

- Features: Compared with DC servo, AC servo has the advantages of high power density, high efficiency and low maintenance cost.

- Application field: It is commonly used in industrial automation, mechanical processing and other fields, and has broad application prospects.

3. Stepper servo system:

- Definition: Stepper servo system uses stepper motor to achieve position and speed control.

- Features: It has the characteristics of simple structure, low cost and high precision.

- Application field: It is commonly used in applications that require high positioning accuracy, such as printing machinery, textile machinery, etc.

These three types of servo systems each have their own unique advantages and scope of application, and can meet the needs of different industrial fields for high-precision, high-performance motion control. 

With the continuous development of servo technology, these systems are also constantly optimized and improved to adapt to more complex and diverse application scenarios.
