Servo motor & # 8203; Since the German industrial 4 is put forward. After 0, our country also puts forward & other; Throughout 2025 & made in China; Design, the acceleration of follow step automation in our country, the future China will become a super robot power, greatly increased demand for industrial robot. In industrial robots under the influence of high growth, however, the main products of the servo motor development of automation control system and the road changes will occur, servo motor as power system of the industrial robot and robot motion & otherHeart & throughout; , where is the future? The 2015 -Global industrial robot servo motor industry report 'in 2019, beginning in 2013, become the largest industrial robots in the international market in our country, the surge in sales in 2014 to 55% of the world's servo motor sales. Estimates that by 2019, China's market demand for servo motor will reach 182000 units. The rapid growth of the industrial robot has been bound to extent influence the development of the servo motor market. According to Researchand Markets, 90% of the industrial robot using servo motor, at the same time, each servo motor of industrial robot device is uniform, so in 2014 the growth of demand for servo motor in our country in 231000. And that number is expected to reach 737000 units in 2019. Now, in the industrial machine market in China, 85% of the servo motor is a foreign brand, and in their own enterprises, most is in a stage of research and development experiment, almost no industrialized industrial robot servo motor. Industrial robot contact with the coexistence of the servo motor servo motor general gear in the robot's & other; The joints & throughout; , robot joints drive is dependent on the servo system, the more joints, the robot's flexibility and precision is higher, the more the number of the servo motor to be used. Robot is very strict to the requirement of joint drive motor, which is also very strict to the requirement of electric servo drive system, mainly has the following several aspects: 1, fast echo, the higher the electrical servo system of sensitivity, fast echo function better; 2, starting torque, moment of inertia is big, in the case of driving load, the requirement of the robot servo motor starting torque, moment of inertia of small; 3, have sex and linearity of handling characteristics, follow the change of the control signal, the speed of the motor can be changed successively, sometimes still need speed is proportional to the control signal or approximation is proportional to the wide scale of speed regulation, and can be used in the latter ~ 10000 speed scale; 4, small volume, low quality and short axial dimensions, the bodily form with cooperative robot; 5, to be endured harsh working conditions, can be very frequent direction and deceleration operation. Other, because domestic servo motor to be promotion, can lead to the development of domestic robots. The status quo of domestic servo motor now is that small, not small little big! How do you understand this? Small power servo motor, miniaturization, in slightly long, light load for example robot servo motor of 200 w and 400 w, now the TBL - sichuanImini series servo micromotor, panasonic A6, yaskawa & Sigma; 7 fine motor short. In contrast, domestic servo, throughout a long, rough appearance. This is on the use of some advanced, especially in light load on the desktop robot 6 kg, because robot arm device space is very narrow, have strict requirements on the length of the servo motor. Second is the reliability of the signal connector has endured. Domestic servo needs continuous improvement, and connectors of miniaturization, high density is also a trend, and servo motor ontology integration design is a very good idea, now Japanese servo motor that is what a lot of design, convenient equipment, debugging, replacement. Another center of servo motor technology is a high precision encoders, especially on the robot with multiple ring absolute value encoder, serious rely on imports. Do not complete the localization, the great bottleneck of the development of our advanced servo system. Encoder miniaturization and servo motor miniaturization around is not the center of the technology in the past. Throughout the change of the Japanese servo motor products are accompanied with coordinated development of the motor magnetic circuit and encoder promotion! Now domestic servo motor OEM manufacturer on the basis of market share, is mostly copy Japanese servo motor design, more power within the 3 kw, in small and medium-sized power. And 5. 5 -15 kw of high-power servo, leading to the use of some devices, because there is no a powerful servo motors and drives, and were forced to abandon the system as a whole. Summary, Japanese servo system is the development form of hierarchical coordination development, all the function is excellent, with Japan's robot development is very similar. In our country is doing motor do motor, encoder encoder, do drive, drive not joint together, lead to all the functions of servo motor and drive system is difficult to do. Followed by the servo system is lack of basic research, including absolute value encoder technology, high-end production technology, production process of the industrialization of the motor of the breakthrough, function index of the practical test and inspection specifications. All of these demand robot industry center parts enterprises to perfect.
