The connection between stepping motor and industrial manipulator

The connection between stepping motor and industrial manipulator stepping motor is usually installed on the robotJoints' At the same time, the Joint Controller of the robot is indispensable to the servo control system. The larger the joint, the higher the rigidity and accuracy of the robot, and the more the total number of stepping motors to be applied. The robot's regulations on the motor of the Joint Controller are very strict, so the regulations on the three-wheel servo controller system are also very strict. The key points are as follows: 1. Rapid abnormality, the higher the coordination of the electric servo control system, the better the rapid occurrence of abnormal characteristics; 2. The ratio of starting torque to inertia is large. Under the condition of controller load, it is stipulated that the starting rotation of the stepping motor of the robot is extremely large and the moment of inertia is small; Stepping Motor 3. The persistence and parallel linearity of the control characteristics, along with the change of the control signal, the number of revolutions of the motor can continue to change. Occasionally, the number of revolutions needs to be positively correlated with the control signal or the similarity is positively correlated, and the range of speed change is wide, can apply 1:1000 ~ The variable speed category of 10000; 4, light weight, small quality, short radial specifications, to coordinate the robot's body; Shenzhen ruite electromechanical Technology Co. , Ltd. is located in Shenzhen, Guangdong province, it is a stepping motor manufacturer integrating research and development, production and sales of stepping motor drivers, servo drivers, stepping motors, servo motors and spindle servo motors. 5, can withstand the harsh operating standards, can carry out very frequent forward and reverse operation and speed down operation. Shenzhen ruite electromechanical Technology Co. , Ltd. is located in Shenzhen, Guangdong province, it is a stepping motor manufacturer integrating research and development, production and sales of stepping motor drivers, servo drivers, stepping motors, servo motors and spindle servo motors. On the other hand, because the domestic stepping motor still needs to be upgraded, the transformation of the domestic stepping robot is difficult. At present, the current situation of stepping motors in China is that the small ones are big, the big ones are small! How do you understand this? Stepping motors with small thermal efficiency are not practical and widely long, such as 200W and 400W stepping motors commonly used by light-load robots, and TBL- ImiNI series servo micromotor, Konka A6, Yaskawa & Sigma; The motor is short and exquisite. Looking at the National servo, the servo is wide and long, and the appearance is not smooth. This is not good in some high-end applications, especially on desktop robots with light load of 6kg or so, because the installation and clearance of the robot's arm is very narrow and has strict requirements on the length of the stepping motor. The second is that the credibility of the signal connector has always been criticized. The servo system in China must be improved again, and the practicality and densification of connectors are all trends. It is a very good method to arrange with the internal modularization of stepping motors. At this stage, many Japanese and Korean stepping motors are arranged in this way, it can be adjusted, adjusted and replaced. Another key technology of stepping motor is servo motor with high precision, especially the multi-turn absolute value encoder placed on the robot, which relies heavily on the servo port. Didn't have keep localization is contain, China high-end servo control system transformation of big short board. The practicality of servo motor is the key technology that stepping motor can not be used in practice. An overview of the replacement of Japanese and Korean wind stepping motor products is accompanied by the cooperative transformation of motor magnetic circuit and servo motor! At present, according to the market share, most of China's stepping motor OEM manufacturers are imitating Japanese and Korean wind stepping motors. The thermal efficiency is mostly within 3kw, with small and micro thermal efficiency being the majority. And 5. 5- There are several kilowatts of 15kw servo motors, resulting in the use of some facilities, because there are several kilowatts of stepper motors and controllers for each set, and the whole system has to be abandoned. In summary, the transformation mode of Japanese and Korean wind servo control system is hierarchical cooperation transformation, with excellent overall characteristics, which is very similar to the robot transformation in South Korea. In our country, the motor is the motor, the servo motor is the servo motor, and the controller is the controller. There is cooperation and coordination between the controllers, resulting in the failure of the overall characteristics of the stepping motor and the controller system. Secondly, the servo control system lacks comprehensive discussion, including absolute value encoder technology, large-scale production technology of high-grade motors, overcoming of processing technology, application certification of performance parameters and formulation of assessment standards. This kind of company must be a key spare part company in the robot manufacturing industry. TAG stepping motor, industrial manipulator
