Stepper motor has good controllability, so it is used as a drive source for various automation equipment. The combination of the stepper motor and the ball screw, known as the ball screw linear stepper motor, converts the rotational motion of the motor into linear motion, or converts the torque into the axial repeated force, while having the characteristics of high efficiency, high precision, high rigidity and long life. Therefore, the ball screw stepper motor is widely used in various precision instruments, electronic equipment and CNC machine tools and other industries.
    leesn Xiaobian summarizes the two advantages of ball screw linear stepper motor

1、 high transmission efficiency
   The transmission efficiency of the ball screw configured with the vertical three-line stepper motor is more than 90%, and the torque required to convert the rotating motion into a linear motion is only 1/3 of that of the ordinary screw, or even smaller.

Positive efficiency (rotation → line)

2、 minimal axial clearance, high precision, high rigidity

    The ball screw equipped with the vertical three linear stepper motor adopts the Gothic groove, the axial clearance is very small, and the nut can run easily and smoothly. If appropriate prepressure is added, the axial clearance can be reduced and the rigidity of the ball screw can be increased.
   The above two points are the advantages of ball linear stepper motors, because of the characteristics of compatible stepper motors, making it widely used in major industries.
