Abstract:

Article Preview

Permanent-magnet linear synchronous motor (PMLS-M) exist the problem of normal force fluctuation, especially in the servo feeding system of high-precision CNC machine tools, the normal force fluctuation can cause the feeding table in vibration and produce resonance with other moving components of the servo feeding system .Analysis shows that detent force fluctuation is the predominant factor. Adopt the methods of end-teeth optimization combine with skew or V-skew can effectively reduce the detent force fluctuation. By using the Fourier regression analysis and limited enumeration method to calculate the optimal parameters, and applying the layered finite element analysis for simulation. The results of simulation prove that with the precondition of the thrust force loss slightly, adopt those optimization methods can reduce the normal force fluctuation significantly.
