Type 57 stepper motor _ deceleration stepper motor price
industrial robot control system and automation products, mainly involving the servo motor, reducer, controller and sensor etc. Servo motor is the dynamic system of industrial robots, generally in the robot & other; The joints & throughout; , is the robot movement & other; Heart & throughout; 。
robot joints drive is dependent on the servo system, the more joints, the robot's flexibility and precision is higher, the more you will have to use the number of servo motor. As actuators of the control system, electric servo drive system constitute one of the three core components of the industrial robot. Electric servo drive system is to use a variety of motor torque and power, directly or indirectly driven robot ontology to obtain various kinds of sports of the robot actuator, usually consists of a servo motor and servo drives. Besides can speed and torque control, servo system can accurately and fast, stable 臵 control.
robot is very strict to the requirement of joint drive motor, thus is also very strict to the requirement of electric servo drive system, mainly has the following several aspects:
1) Quick responsiveness, the higher the electrical servo system of sensitivity, rapid response performance is better.
2） Starting torque moment of inertia than the big, in the case of driving load, requirements of the robot servo planetary gear motor starting torque is big, the moment of inertia is small.
3） Control characteristics of the continuity and linearity, as the change of control signal, the speed of the motor can change continuously, sometimes still need speed is proportional to the control signal or approximation is proportional to the, wide speed range, can be used in the latter ~ 10000 speed range.
4） Small volume, low quality and short axial dimensions, to match the size of the robot.
5） Able to withstand harsh operating conditions, can be very frequent direction and deceleration operation, and can in a short period of time several times under overload. Ac servo drive because of its high torque moment of inertia ratio, and the advantages of no brush and commutation spark, is widely used in industrial robots. Eph company wei intelligent service robot ResearchandMarkets issued a 2015 - Global industrial robot servo motor industry report in 2019. Report shows that since 2013, China became the world's largest industrial robot market, the surge in sales in 2014 to 55% of the sales of the servo motor in the world, a total of 57000 units. With the industrial upgrading, and the robot to replace human labor demand, driven by China's industrial robot market will continue to grow rapidly, by 2019, the Chinese market demand for servo motor will reach 182000 units. The rapid growth of the industrial robot has to a certain extent, to stimulate the development of the servo motor market. According to ResearchandMarkets estimates, 90% of the industrial robot using servo motor, at the same time, each industrial robot assembly of servo motor is average, 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.
at present, the industrial machinery market in China, 85% of the servo motor is a foreign brand, including mainstream suppliers, panasonic, yaskawa, mitsubishi, Japan and Europe and the United States of lorentz and Bosch rexroth. Among them, 2015, the Japanese brand occupies the largest market share in China & ndash; — Nearly 50%. Most Chinese companies, however, is still in the research and test phase, almost no industrialized industrial robot servo planetary gear motor. In order to reverse this situation, China's enterprises, including automation and inovance ace, a few companies, such as in the recent years continuously break through technical bottlenecks, to strengthen the construction of product research and development and industrialization projects.
The manufacture marketing game of electric motor suppliers is changing with each innovation, and businesses of all products need to be ready to pounce.
Energetic, optimistic entrepreneurs often tend to believe that sales growth will take care of everything, that Hangzhou Xiaoshan Zhenyu Transmission Co., Ltd. will be able to fund our own growth by generating profits.
Always put quality over cost is the rule of thumb if you want to buy a really durable and reliable . But with Hangzhou Xiaoshan Zhenyu Transmission Co., Ltd., you can have the same.
