Servo drive is also known as the "servo controller", "servo amplifier", the working principle is used to control the servo motor of a controller, its role is similar to the inverter acting on the ordinary brushless dc servo motor, belongs to a part of the servo system.
Precision: The brushless dc servo motor with driver realizes the closed-loop control of position, speed and torque, and overcomes the problem of step motor loss.
Brushless dc servo motor with driver mainly used in the high-precision positioning system.
