A comparison between linear motors and rotary motors!
Compared with rotary motors, linear motors have the following main characteristics:
First, the structure is simple. Since linear motors do not require additional devices to convert rotary motion into linear motion, the structure of the system itself is greatly simplified, and the weight and volume are greatly reduced.
Secondly, it has high positioning accuracy. In places where linear motion is required, the linear motor can achieve direct transmission, thus eliminating various positioning errors caused by intermediate links, resulting in high positioning accuracy. If microcomputer control is used, the positioning accuracy of the entire system can be greatly improved.
Third, it has a fast response speed, high sensitivity, and good follow-up performance. Linear motors can easily make their movers supported by magnetic levitation, thus ensuring that there is always a certain air gap between the movers and stators without contact. This eliminates the contact friction resistance between the stators and movers, thereby greatly improving the system's sensitivity, speed, and follow-up performance.
Fourth, it is safe, reliable, and has a long service life. Linear motors can transmit force without contact, and mechanical friction loss is almost zero, so there are few failures and no maintenance is required, thus making them safe, reliable, and long-lasting.
Because linear motors have so many advantages, we have every reason to believe that their development will be even better!
