Electrical network & # 8203; With independent intellectual property rights of core technology, is the enterprise's & other; 'Ming & throughout; Location. With the rising and development of modern industrial technology, the level of intelligent manufacturing has become a manufacturing powerhouse, one of the important signs of industrial robots is the core of intelligent manufacturing performance of the layer equipment, is a complete intelligent hardware foundation of making the final production stage is also a representative of advanced manufacturing products. Due to the lack of core technology, industrial robots in China core parts imports servo electrical pilot time, limiting the development of robot industry in China. 'Made in China 2025' planning overall arrangement of the robot servo motor policy: by 2020, function, accuracy, reliability, reach the level of similar foreign products. In order to change this forced situation, gree from power density, the cogging torque and current loop planning three aspects, such as, independently developed the industrial robot with high function and servo motor drives, assessments expert group evaluation of scientific and technological achievements, the overall technology reach & other; Throughout the world's advanced &; Level, servo motor function such as power density, overload ability index reach & otherThroughout the world's leading &; Level. So, the self-developed gree industrial robots with servo motor, what are the good place? 1, low torque ripple, positioning precision is well known, the positioning precision of servo motor is an important indicator, and the torque ripple is to ensure that the positioning accuracy is an important factor. Gree industrial robot with servo motor through a self-developed low cogging torque and torque ripple system planning technology, useful down servo motor cogging torque and torque ripple, further improve the control accuracy of servo system, the cogging torque and torque ripple of the motor function, can be comparable to the industry first-class enterprise. 2, low torque ripple, positioning precision of traditional servo motor used for general brake, solidification structure, motor miniaturization is limited. Therefore, gree self-developed brake, the opposite sex to make the servo system of collaborative planning overall effect, make the motor structure more compact, gree industrial robots with servo motor machine length is only 111 mm, shorter than a tin of coke, leading the industry, the power density is as high as 282. 5 w/kg, as my career. The deployment of 20 - high resolution absolute value encoder, greatly improved the flexibility and accuracy of industrial robots. 3, wide operating range, stable running gree industrial robot with servo motor has wide scale operation, and the top speed of 6500 r/min, instantaneous overload capacity is 3. 5 times the rated torque to the industry the highest level, greatly improve the servo motor ability to cope with different load requirements, motor using a further enhanced reliability and safe sex. 4, good temperature characteristics, safe and reliable with motor power density increase and structure miniaturization, motor temperature rise overruns became the primary bottleneck. Gree industrial robot with servo motor selection system of the axial heat transfer path planning technology, to ensure the high power density of the servo motor, miniaturization, reasonable scale to control the motor temperature rise. Core technology without tooth yoke separate stator core buckle dot brake adhesive structure and engineering technology and the motor end cover integration planning technology axial heat transfer system planning technology to lower the cogging torque and torque ripple system planning technology as a national enterprise, gree, don't forget to beginner's mind, remember, always insist on the development of independent innovation, and constantly to autonomous core technology provided strong impetus to the industrial development of our country, for more given to our country enterprise, promote the change from manufacturing power to manufacturing powerhouse. In the future, gree will be made on the vision to carry out the continuous, & other; With the key generic technology, cutting-edge led technology, modern engineering technology, disruptive technologies made different as the breakthrough point, have the courage to walk predecessors' no path, efforts to achieve the key core technology independent controllable, the different initiative, to develop firmly grasp the initiative in our own hands. ”
