Linear motor compared to rotating electric machine
Compared with rotating electric machines, linear motors have the following characteristics:
First, the structure is simple, because the linear motor does not need to turn the rotary motion into an additional device for linear motion, so that the structure of the system itself is greatly simplified, and the weight and volume are greatly reduced;
Second, the positioning accuracy is high. In places where linear motion is required, the linear motor can realize direct transmission, thus eliminating various positioning errors caused by intermediate links, so the positioning accuracy is high, and if using microcomputer control, it can be greatly improved. Positioning accuracy of the entire system;
Third, the reaction speed is fast, the sensitivity is high, and the follow-up is good. The linear motor is easy to support the magnetic levitation of the mover, so that a certain air gap is always maintained between the mover and the stator without contact, which eliminates the contact frictional resistance between the stator and the mover, thereby greatly improving the system. Sensitivity, rapidity and follow-up;
Fourth, work safe and reliable, long life. The linear motor can realize the contactless transmission force, and the mechanical friction loss is almost zero, so the fault is small and maintenance-free, so the work is safe and reliable, and the service life is long.
