Linear modules are different from linear motors . The two are some active transmission components, which can achieve linear motion, that is, assemble various parts on aluminum profiles and cover plates, and the appearance looks very similar.
1. Differences in the principle of linear motion
Although the appearance is similar, the principles of linear motion are different. The linear motor directly converts electrical energy into mechanical energy and reaches linear motion without central arrangement. Linear modules require the use of ball screws or synchronous belts to convert curved motion into linear motion.
2. Poor accuracy
Linear motors have higher accuracy than linear modules. The structural characteristics of linear motors are simple, and they directly generate linear motion without requiring central transformation arrangements. The moment of motion inertia was reduced, and the dynamic care function and positioning accuracy of the system were greatly trekked.
3. Differences in speed
Linear motors have great speed characteristics. The linear motor speed is 300m/min; the acceleration is 10g. The ball screw speed is 120m/min; the acceleration is 1.5g. Compared with speed and acceleration, linear motors have very great benefits. In addition, after the thermal problem is successfully processed, the linear motor speed will further trek. However, the speed of the "rotating servo motor + ball screw" is bound by many and difficult to travel. In terms of dynamic care, linear motors have absolute advantages due to inertia, voids and arrangement complexity.
4. Differences between noises
The noise of linear motors is smaller than that of linear modules because the linear motor is not bound by centrifugal force and does not have mechanical contact when moving, so there is no conflict or noise. The transmission assembly is free of wear and can reduce mechanical losses at a high level, prevent noise caused by cables, steel cables, gears, pulleys, etc., and then travel through the entire power.
5. Price difference
The function of linear motors in all aspects is that they are higher than linear modules. Therefore, in terms of price, linear motors are more expensive, generally several times more expensive.
These are the primary differences between linear modules and linear motors. Of course, in addition to these differences, the drivers are also equipped with different equipment. The linear module is a servo motor or a stepper motor control, while the linear motor itself is the driving device.
