Interpretation of the concept of servo motor, Japanese companies occupy half of the robot motor
The 2017 World Robotics Conference ended in Beijing International Exhibition Center. ABB, FANUC, KUKA, Yaskawa, Shinsong, Harbin Institute of Technology robots, Guangzhou NC, Kangli Youlan, and Ubisoft selected well-known domestic and foreign companies to compete on the same stage. Surgical robots, piano robots, intelligent collaborative robots, bionic jellyfish, bionic arms, etc. make the audience stunned. The normal operation of the robot is inseparable from the servo motor. The robotic electric servo drive system is the actuator that directly or indirectly drives the robot body to obtain various movements of the robot by using the torque and force generated by various motors, usually by servo motor and servo. The drive consists of. Industrial upgrades have given Chinese robot motor manufacturers the opportunity and challenge. Compared with the advanced manufacturers in Europe and America, we still have a gap. The non-network small series will summarize the world's major robot servo motor manufacturers. Let us look at the robot servo motor. The status quo of the industry.
A servo motor is an engine that controls the operation of a mechanical component in a servo system, and is an auxiliary motor indirect transmission.
The servo system, also known as the servo system, is a feedback control system used to accurately follow or reproduce a process. The servo system enables an automatic control system in which the output control amount of the object, such as the position, orientation, state, etc., can follow any change in the input target (or given value). Its main task is to control the power, to transform, transform and control the power according to the requirements of the control command, so that the torque, speed and position control of the drive device are very flexible and convenient. In many cases, the servo system refers to a feedback control system in which the controlled amount (output of the system) is mechanical displacement or displacement velocity and acceleration, and its function is to make the mechanical displacement (or rotation angle) of the output accurately track the displacement of the input ( Or corners), the structural composition and other forms of feedback control systems are not in principle different.
Servo motor classification
Servo motors are divided into two major categories: DC and AC servo motors. Compared with ordinary motors, the main features are that they are usually used together with feedback devices to achieve precise control.

Japanese companies occupy half of the countryJapan has always been a powerful robot, so Japan's servo motor industry is also the world's top. According to the 2016 Global Market Research Report of the research institute, Japanese companies account for 50% of the market, occupying half of the entire robotic motor industry.
