Can linear motors completely replace screw modules? In the past two years, with the rapid development of linear motors, there have been constant claims in the industry that linear motors will replace traditional ball screw modules. As someone who has been in the industry for more than ten years, let's analyze whether linear motors can completely replace traditional ball screw modules?

Firstly, from a cost perspective, the price of a linear motor with a 1-meter stroke is currently around 10000 yuan, while the price of a ball screw with the same stroke of around 4000 yuan still has a significant difference. Although the cost of linear motors continues to decrease, it still takes a considerable amount of time.

Secondly, from an application perspective, the characteristics of linear motors include high acceleration, fast response, and long travel. However, some drawbacks of ball screws, such as length limitations of around 4m, mechanical clearances, friction losses, thermal distortion, and periodic errors in pitch wear, have led to the flourishing development of linear motors.

Thirdly, with the continuous development of high precision and cutting-edge technology in the semiconductor industry in recent years, the performance of traditional screw modules in processing equipment such as lithography machines, IC bonding machines, and IC plastic packaging machines is getting closer and closer to its limit, which has provided assistance to linear motor modules.

The ball screw module plays an irreplaceable role:

1. When used vertically, the linear motor module cannot be compared to the ball screw, and a similar combination is a combination of linear motor and ball screw module.

2. The characteristics of load force and mechanical transmission are similar to overloading, just like the overclocking use of early computer CPUs. The overclocking force of the ball screw module is very strong, sometimes increasing the motor force, while the maximum thrust of the linear module cannot be exceeded.

3. Heat dissipation and energy consumption are higher than traditional ball screws.

In summary, the development of linear motors is unstoppable, and their proportion in the transmission field will gradually increase. The screw module will not be completely defeated, and it may even be used in combination with its own characteristics. We hope to have one of the three markets in the transmission field for the development of linear motor modules.
