Servo driver, also known as “servo controller” and “servo amplifier”, is a controller used to control the servo motor. Its function is similar to that of a frequency converter acting on an ordinary AC motor. It is a part of the servo system and is mainly used in high-precision positioning systems. Generally, the servo motor is controlled by three methods of position, speed and torque to achieve high-precision positioning of the transmission system. It is currently a high-end product of transmission technology.
1. Requirements for the servo drive to the system.
(1) Wide range of speed regulation;
(2) High positioning accuracy;
(3) Sufficient transmission rigidity and high stability of speed ;
(4) Quick response, no overshoot.
(5) High torque at low speed, strong overload capacity.
(6) High reliability
2. The servo driver requirements to the motor.
(1) The motor can run smoothly from the lowest speed to the highest speed, and the torque fluctuation should be small. Especially at low speed such as 0.1r/min or lower speed, there is still a stable speed without creeping phenomenon.
(2) The motor should have a large overload capacity for a long time, to meet the requirements of low speed and high torque. Generally, DC servo motors are required to be overloaded 4 to 6 times within a few minutes without damage.
(3) In order to meet the requirements of fast response, the motor should have a small moment of inertia and a large stall torque, and should have the smallest time constant and starting voltage as possible.
(4) The motor should be able to withstand frequent starting, braking and reversation.
