The growth of the robotics industry is in full swing and blooming. A large number of machine tool manufacturers, servo manufacturers and other qualified companies have all turned to the robot market. Why are the machine tool manufacturers and servo manufacturers making such positive transformations in R&D robotics? Industrial robots have four major components, namely body, servo, reducer and controller.
Stepper motors are used to drive the joints of robots. Requirements are to have a maximum power-to-mass ratio and torque inertia ratio, high starting torque, low inertia and a wide and smooth speed range.
As the robotics industry grows, it is necessary to make breakthroughs in areas such as servos and integrated control. At present, China is still in the stage of breakthrough in the field of servos and so on, which has an adverse impact on the local robot industry.
The general structure of an industrial robot's electric servo system is three closed-loop controls, namely a current loop, a speed loop, and a position loop. Under normal circumstances, for AC servo drives, various functions such as position control, speed control, and torque control can be achieved by manually setting the internal function parameters.
With the continuous advancement of industrial automation, the demand for automation software and hardware equipment has remained high, and the domestic industrial robot market has been steadily growing. It is expected that China will become the world's largest demand market in 2015.
At the same time, it directly drives the market demand for servo systems. The Minzhi stepping servo motor system supplied by Mickey perfectly integrates the servo control technology in the integrated motor, and has the characteristics of high precision, good stability, and high speed.
At present, AC and DC servo motors with high starting torque, large torque and low inertia are widely used in industrial robots. Other motors, such as AC servo motors and stepper motors, will also be applied to industrial robots according to different application requirements.
In particular, robot end effectors (grippers) should use motors with the smallest possible volume and quality. Especially when fast response is required, servo motors must have high reliability and large short-term overload capability. Specific use requirements:
Rapidity.
The starting torque inertia ratio is large.
The continuity and linearity of the control characteristics, with the change of the control signal, the speed of the motor can continuously change, and sometimes the speed and the control signal must be proportional or approximately proportional.
Wide speed range.
Small size, low mass, short axial dimension.
Can stand up to harsh operating conditions, can perform very frequent forward and reverse and acceleration and deceleration operations, and can withstand overload in a short time.
Shantui lumbering bulldozer is researched and developed in response to the forest working environments, in which the forward extended rollover protection structure can effectively protect the whole machine and the working device features light and flexible operations. It`s applicable for the operations in lumbering sites.
