What is a Servo Ball Screw?

The ball screw connected to the servo motor is usually called a servo ball screw. It can convert the motor's rotational motion into linear motion and is widely used in the field of automation.

1. Working Principle of Servo Ball Screw

A servo ball screw is a device that converts the rotational motion of a servo motor into linear motion. It is usually composed of a motor, a reducer, a screw, a guide rail, and a feedback device.
In a servo system, the torque and speed output by the motor are reduced by the reducer and converted into linear motion by the screw. The linear motion of the screw will drive the load on the guide rail to move. During the movement, the feedback device will feed back the position information of the load to the controller. The controller will adjust the torque and speed output by the motor according to the feedback signal, thereby controlling the position movement of the load.

2. Advantages and Characteristics of Servo Ball Screw

The servo ball screw has the following advantages and characteristics:

• High Precision

The position control accuracy of the servo screw is high, and micron-level positioning can be achieved, which greatly improves the accuracy and stability of the production line.

• High Speed

The servo ball screw can complete fast and efficient linear motion, which is suitable for high-speed processing of automated production lines.

• High Efficiency

The servo ball screw converts the motor output speed into a suitable screw speed through a reducer, thereby improving the conversion efficiency and reducing energy consumption.
