What is a ball screw servo motor

Ball screw servo motor is a driving device that combines a servo motor with a ball screw, mainly used to convert the rotational motion of the motor into linear motion. Ball screw servo motor system usually consists of servo motor, ball screw, supporting bearing, and guiding device, etc., which have the characteristics of high precision, high efficiency, and low friction

Working principle

The working principle of ball screw servo motor is based on the mechanical transmission characteristics of ball screw. The servo motor provides rotational power and converts rotational motion into linear motion through a ball screw. The rolling of the ball between the screw and nut reduces friction, improving transmission efficiency and accuracy

Application scenarios

Ball screw servo motors are widely used in various applications that require precise linear motion, such as CNC machine tools, industrial robots, automated production lines, etc. Due to its high precision and high efficiency, it is particularly suitable for applications that require high-precision positioning and control

Merits and demerits

Advantages:

High precision: Due to the low rolling friction of the ball screw, the transmission accuracy is high.

High efficiency: High transmission efficiency and fast response speed.

Low friction: reduces mechanical wear and extends equipment life.

Easy to control: with servo motors, precise position and speed control can be achieved

Disadvantages:

High cost: Compared to traditional transmission methods, the cost of ball screw servo motors is higher.

Complex maintenance: requires regular maintenance and upkeep to ensure high precision and long lifespan
