The servo motor is also known as the executive motor. In an automatic control system, it is used as an execution element to convert the received electrical signal into an angular displacement or angular speed output
on the motor shaft.
In order to make the robot more accurate and efficient work, so, we for the servo motor accuracy, speed, torque and other requirements are very high. In addition to the above main advantages, the servo motor and the common motor in our daily life also have a big difference, the ordinary motor, after the power failure, it will turn for a while because of its own inertia, and then stop. And the servo motor is said to stop to stop, said to go away, very fast reaction.
Precision: realize the closed loop control of position, speed and torque; overcome the problem of stepping motor;
Speed:good high-speed performance
Industrial robot control system and automation products mainly involve servo motor, reducer, controller and sensors. Servo motor is the power system of industrial robots, which is generally installed in the "joint" of the robot, which is the "heart" of the robot movement.
