The linear module is an automatic transmission element, which uses timing belt or ball screw to drive the slider to move. It is usually composed of timing belt, ball screw, direct moving die, aluminum alloy profiles, ball screw bracket, coupling, motor, Photoelectric switch and other components. Both linear modules and linear motors are automatic transmission components, which can achieve linear motion. They are all assembled on aluminum profiles and covered with a cover, which looks similar in appearance. Let's take a look at the advantages of linear modules, which are roughly as follows:
1. Difference in accuracy
Its accuracy is higher than linear motor, and its structure is simple. It does not need to go through the intermediate speed change mechanism to directly move linearly, which reduces the inertia of motion, greatly improves the dynamic response performance and positioning accuracy, and can reach an accuracy of 0.001mm. The accuracy of linear motors is generally between 0.005 and 0.04 mm.
2. Distinguish the principle of linear motion
Although the appearance is similar, the principle of linear motion is different. The linear motor is directly converted from electrical energy into mechanical energy. There is no need for an intermediate mechanism to realize linear motion, while the linear module needs to use a ball screw or a timing belt to convert the curved motion into a straight movement.
3. The difference in noise
Because the linear motor has no centrifugal force constraint, no mechanical contact, no friction, and no noise during movement, the linear motor is less noisy than the linear motor. The drive components are free from wear, which greatly reduces mechanical loss, avoids the noise generated by towing cables, steel cables, gears and pulleys, and improves overall efficiency.
4. Speed difference
Linear motors have great advantages in terms of speed. Compared with acceleration motors, linear motors have considerable advantages in terms of speed and acceleration. After the linear motors successfully solve the heating problem, the speed will be further improved, while the "servo motor + ball screw" will be more affected in terms of speed. It is difficult to increase the limit.

We all know that linear guides are now an important part of mechanical equipment. Be careful when using linear guides. Many factors will affect the guides and make them fail during operation! Today I will introduce you to the influence of temperature on linear guides! The influence of temperature oRead More
The relationship between the pre-pressure of the ball screw and the load of the screw is mainly used for gap adjustment. If high precision is required, the pre-pressure should be increased accordingly, but it should not be too large, otherwise it will cause high temperature and reduced efficiency.Read More
What is the ball screw drive torque? How should this torque be calculated? The torque of the mechanical components is called the driving torque of the ball screw. The ball screw will produce a certain degree of torsional deformation under the action of torque. Torque is the basic load form of transmRead More
