Paper Title:
Research on Permanent Magnet Linear Motor without Friction Feed
  Abstract

In order to eliminate the friction of the feed system in NC Machine Tools, this paper presented a novel direct magnetic levitation permanent magnet linear motor. First, the structure and magnetic levitation theory of the direct magnetic levitation motor were discussed. Second, on the basis of the motor magnetic hierarchical model, the expression of the magnetic field and the electromagnetic force was derived by the virtual displacement method. Finally, no-load magnetic field, load air-gap flux density and the electromagnetic force of the motor were simulated by using Ansoft Maxwell 2D software. The results of simulation test indicated that using direct magnetic levitation permanent magnet linear synchronous motor can realize the friction-free feed of NC Machine Tools.
