Comparison between linear motors and conventional rotary motors
Compared with traditional rotary motors, linear motors have the following characteristics:
●1 Simple structure: Since the linear motor does not need to add the rotary motion to the linear motion, the structure of the system itself is greatly simplified, and the weight and volume are greatly reduced;
●2 High positioning accuracy: In places where linear motion is required, linear motors can realize direct transmission, thus eliminating various positioning errors caused by intermediate links, so positioning accuracy is high, such as using microcomputer control, it can be greatly improved. Positioning accuracy of the entire system;
●3 Fast response speed, high sensitivity and good followability: Linear motors are easy to support the magnetic suspension of their movers, so that there is always a certain air gap between the mover and the stator without contact, which eliminates the fixed, Contact frictional resistance between the movers, thus greatly improving the sensitivity, rapidity and follow-up of the system;
●4 Safe and reliable work, long service life: Linear motor can realize non-contact transmission force, mechanical friction loss is almost zero, so the fault is less, maintenance-free, so the work is safe and reliable, and the service life is long.
