Servo system is an automatic control system, it makes the object position, direction and state of the output controlled quantity follow the input target (or given value) of any change. Servo mainly by pulse positioning. Basically, it can be understood that when the servo motor receives the pulse, it will rotate an angle corresponding to the pulse to achieve displacement. Since the servo motor itself has the function of sending pulses, the servo motor will send a corresponding number of pulses every time it rotates an angle, which corresponds to the pulses received by the servo motor, or is called a closed loop. In this way, the system will know how many pulses are sent to the servo motor and how many pulses are received at the same time.
The relationship between robot and servo motor
2020-11-18
As the core component of industrial robot, servo motor is the "heart" of industrial robot power system and motion system ". The joint drive of the robot is inseparable from the servo system. The more joints, the higher the flexibility and accuracy of the robot, and the more servo motors are used. The servo system is very demanding. It must meet the requirements of fast response, high starting torque, large torque-to-inertia ratio, and large speed range to adapt to the robot's small size, light weight, acceleration and deceleration operation conditions, and high reliability. and stability. Currently, most industrial robots use AC servo motor systems.
What are the characteristics of electro-hydraulic servo system
2020-11-06
Electro-hydraulic servo system has many advantages, the most prominent of which is fast response, large output power and high control accuracy. Therefore, it has been widely used in aviation, aerospace, military, metallurgy, transportation, engineering machinery and other fields. Electro-hydraulic servo technology is the best technical means to realize dynamic high cycle fatigue, programmed fatigue and low cycle fatigue as well as static constant deformation rate, constant load rate and various analog simulation test systems.
The working principle of electro-hydraulic servo system
2020-10-28
Electro-hydraulic servo system is a relatively young industrial technology, an important branch of the field of hydraulic technology, and one of the basic technical components of modern control engineering. There are usually two types of open loop and closed loop. In recent years, as the demand for high-response, high-precision, high-power ratio, and high-power hydraulic control systems in my country's manufacturing industry continues to expand, the research on electro-hydraulic servo control systems has become more and more extensive. Our country has also made great progress.
The difference between high-power servo DC motor and servo AC motor
2020-10-19
What is the difference between servo DC motor and servo AC motor? Because if the servo AC motor is high power, the corresponding motor also uses high voltage, and the servo DC motor can use low voltage even if it is high power. Therefore, high-power servo DC motors are also called low-voltage servo motors.
Development Trend of High Power Servo
2020-10-07
High-power servo systems are used more and more widely, and users have higher and higher requirements for servo drive technology. In general, the development trend of servo system can be summarized as follows: 1. Communication Servo technology will continue to shift rapidly from DC servo systems to AC servo systems. Judging from the current international market situation, almost all new products are AC servo systems. In industrialized countries, the market share of AC servo motors has exceeded 80%. There are more and more AC servo motor manufacturers in China, and they are gradually surpassing DC servo motors. It is foreseeable that in the near future, except in some micro-motors
