The shaft linear motor adopts coreless technology, and the moving stator adopts an eccentric structure design, with a simple structure and light weight, which is easy to install and has good rigidity; the shaft linear motor has fast response, low vibration, and small speed fluctuations. The linear motor will not be able to produce a sudden and cogging effect during high-speed operation, and it has a stable constant speed. Suitable for high speed and high precision positioning applications.
