As China's automation process accelerates, the demand for industrial robots has greatly increased. Stimulated by the rapid development of industrial robots, the demand for their control systems and servo motors (the main products of automation) will also greatly increase. What are the characteristics and advantages of robots using servo motors as the power system of industrial robots?
DC servo motors are generally installed at the "joints" of the robot. The joint drive of the robot cannot be separated from the servo system. The more joints, the higher the flexibility and accuracy of the robot, and the greater the number of servo motors to be used. Robots have very strict requirements for joint drive motors, so they also have strict requirements for electric servo drive systems. As the core component of industrial robots, servo motors have five major advantages:
1. Rapid response. The higher the sensitivity of the electric servo system, the better the rapid response performance;
2. The starting torque to inertia ratio is large. When driving a load, the robot's servo motor is required to have a large starting torque and a small moment of inertia;
3. The continuity and linearity of the control characteristics. As the control signal changes, the motor's speed can change continuously. Sometimes the speed needs to be proportional or approximately proportional to the control signal. The speed adjustment range is wide and can be used at the range of 1:1000~10000.
4. Small size, small mass, and short axial size to match the body shape of the robot;
5. It can withstand harsh operating conditions and can carry out very frequent forward and reverse, acceleration and deceleration operations.
The above is a brief description of the five advantages of servo motors for robots. I hope it can help customers with such applications gain some understanding of servo motors.
