High precision servo motor can be understood as a motor that absolutely follows the control signal command: the rotor is still before the control signal is sent; the rotor rotates immediately when the control signal is sent;and the rotor can stop immediately when the control signal disappears.
Servo driver 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 AC motor, belongs to a part of the servo system, mainly used in the high-precision positioning system. Generally, the servo motor is controlled through the position, speed and torque of three ways to achieve high-precision transmission system positioning, which is currently a high-end product of transmission technology.
High accuracy and strong stability: The servo motor with driver realizes the closed-loop control of position, speed and torque, which not only overcomes the problem of stepping motor loss in operation, but also provides sufficient guarantee for the production and processing of the equipment in terms of accuracy and stability. This advantage is incomparable to the traditional motor.
In addition, the servo motor with driver is widely used in the computer embroidery machine and other textile machinery and equipment.
