Easy to understand! An article briefly describes the common classification of servos, essential knowledge for technicians

Dear technical friends, the steering gear is a common control device in various control systems. With its unique functions and characteristics, it is widely used in many fields such as robots and model aircraft and plays a very important role. Today we are going to talk about the classification of servos in depth.

According to the perspective of power source, servos can be classified into electric servos, hydraulic servos and pneumatic servos. Among them, electric servos are the most common type. They have extremely outstanding advantages. Their structure is relatively simple and low-cost. It is also relatively cheap and responds very quickly. Because of this, it has been widely used in daily electronic production, small robots, model aircraft and many other fields. For example, installing an electric servo on a small model aircraft aircraft can accurately control the flight attitude of the aircraft. This is because after receiving the control signal, the electric steering gear can quickly convert electrical energy into mechanical energy, thereby causing the output shaft of the steering gear to rotate, thereby adjusting the flight attitude.

Hydraulic steering gear has strong power output capability. It is driven by the hydraulic system. It plays a key role in many fields such as large mechanical equipment and ships. When large equipment requires precise control and requires greater power, hydraulic steering gear has undoubtedly become the first choice. In terms of steering gear control of large engineering ships, hydraulic steering gear can provide sufficient power to change the ship's course and ensure safe and stable navigation.

However, due to the complexity of the hydraulic system, the cost of the hydraulic steering gear is relatively high, and its maintenance requires professional and technical personnel.

Pneumatic servos rely on compressed air as a power source to drive and operate. They have outstanding features such as cleanliness, pollution-free, and extremely fast response. Therefore, pneumatic servos have good applicability in some specific occasions that have strict requirements on environmental quality and have certain requirements on equipment response speed.

For example, in automated production lines in industries such as food processing, pneumatic servos can rely on their own advantages to quickly and accurately achieve corresponding control tasks, and fully comply with the strict hygiene requirements of the food processing industry to ensure the safety and hygiene of the production process.

From the perspective of control methods, servos have different types, which can be clearly divided into analog servos and digital servos.Analog servos receive analog signals. The control method of this kind of servos is relatively simple, but its accuracy may be limited to a certain extent.. The digital servo receives digital signals and has the ability to process control signals more accurately, so its control accuracy is higher and its response speed is faster.

In some fields of industrial automation production that have extremely high requirements for precision, the advantages of digital servos are extremely obvious. For example, in the process of precision machining, digital servos can accurately control the movement trajectory of the tool, thereby ensuring that the quality of the product reaches high standards.

Q: Is the electric steering gear suitable for use on large equipment?

Electric steering gear is not suitable because it has relatively small power and is generally used for small equipment. However, most large equipment uses hydraulic steering gear.

The question is as follows. Compared with digital servos and analog servos, does it have better performance? In other words, is digital servos better than analog servos?

Under normal circumstances, digital servos have the characteristics of high precision and fast response, but analog servos have the advantages of simplicity and low price.。

What constitutes a complex but extremely important knowledge system is the classification of servos. Among many technical fields, it is key for technicians to have an in-depth understanding of the classification of servos. This will help them accurately select the servos that meet their needs in actual application scenarios, which can effectively improve work efficiency and product quality.

I hope that in the subsequent work processes, everyone can select the steering gear scientifically and standardly according to the specific actual needs. Let the steering gear show its maximum efficiency, serve us better, and then create more value, help the work continue to move to new heights, and achieve more outstanding results.
