Servo motor from German industrial 4 is put forward. After 0, China is also put forward & other; Throughout 2025 & made in China; Planning, with the acceleration of China's automation steps, the future China will become a super robot power, more demand for industrial robots. Under the stimulus industrial robot high increase, however, the automation control system and the main products of the servo motor road will attack changes, servo motor as the dynamic system of industrial robots and robot motion & other; Heart & throughout; , where is the future? The 2015 -Global industrial robot servo motor industry report 'in 2019, according to the beginning of 2013, China became the world's largest industrial robot market, 2014 sales soared to 55% of the world's servo motor sales. Predicts 2019, the Chinese market demand for servo motor will reach 182000 units. The rapid increase of the industrial robot has surely in the servo motor market. According to Researchand Markets, 90% of the industrial robot using the servo motor, together, each industrial robot assembly of servo motor is uniform, so in China in 2014 to increase the demand for servo motor in 231000. And that number is expected to reach 737000 units in 2019. A big increase in demand for industrial robot servo motor will go? Now, industrial machinery market in China, 85% of the servo motor is a foreign brand, and local companies, most are still in experimental stage development, 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 with joint drive motor, thus 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 than the big, in the case of driving load, requirements of the robot servo motor starting threats, moment of inertia of small; 3. Handling characteristics of succession and linearity, 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, speed size can use 1000 ~ 10000; 4. Small volume, low quality and short axial dimensions, to match the size of the robot; 5. To be endured harsh operating conditions, can be very frequent direction and deceleration operation. Other, because domestic servo motor to be promotion, lead to domestic robots to carry out the difficulties. The status quo of domestic servo motor now is that small, not small little big! How to understand this? Small power servo motor, miniaturization, in slightly long, such as light load robot servo motor of 200 w and 400 w, now the TBL - sichuanImini series servo, panasonic A6, yaskawa electric & Sigma; 7 motor short and fine. In contrast, domestic servo, throughout a long, rough appearance. It 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 demand continues to improve, and connectors of miniaturization, high density is also a trend, and servo motor of the ontology integration planning is a very good practice, now Japanese servo motor that is what many planning, facilities equipment, debugging, replacement. Servo motor of the high-precision encoder is another core skills, special robot in circle of absolute value encoder, serious rely on imports. Do not implement localization, it is a big bottleneck of restricting China's senior servo system. Encoder miniaturization and servo motor miniaturization around is not the core skills of the past. Throughout the change of the Japanese servo motor products are accompanied with the motor magnetic circuit and encoder together to carry out the promotion! Now domestic servo motor OEM manufacturer on the basis of market share, is mostly copy Japanese servo motor planning, 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 was forced to abandon the system as a whole. Summary, the development of Japanese servo system forms are layered together to carry out, all the function is excellent, with Japan's robot is very similar. Motor in China do do motor, encoder do encoder, do drive, drive not joint together, lead to all the functions of servo motor and drive system is difficult to do. Lack of basic research, followed by the servo system contains absolute value encoder skills, high-end motor manufacturing skills, the production process of the industrialization of the break, function index of the practical test and inspection specifications. All of these demand to perfect robot industry core components company.
