Classification of industrial robot motor drive system




Robot electric servo drive system is to use a variety of motor torque and power, directly or indirectly driven robot ontology for the robot's actuators of various kinds of sports.
The drive motor, industrial robot joint requires maximum power quality ratio and inertia torque ratio, high starting torque and low inertia and  more broad and smooth speed range. Especially like robot end actuator motor volume should be adopted, the quality is as small as possible, especially for quick response, servo motor must have high reliability and stability, and has the larger short-term overload capacity.
At present, due to the high starting torque and high torque and low inertia of ac and dc servo motor is widely used in industrial robots, industrial robots under general load of 1000 n mostly adopts electrical servo drive system. Industrial robot drive system adopted by the motor.
