| Abstract |
This paper proposes a simplified and fast
evaluation method of the drive characteristics of Claw-Pole
Type PM Stepping Motors whose dimensions are given. The
proposed method consists of a geometric flux-tube-based
non-linear magnetic analysis and a dynamic simulator based
on an analytical expression of the magnetizing curves
obtained from the non-linear magnetic analysis. The
proposed method allows us to easily take into account
nonlinearities of the core, and to calculate static and
dynamic characteristics, with a dramatic reduction in the
computation time compared to 3D-FEA while keeping
reasonable analytical accuracy. The validity of the proposed
method is verified by experiments and finite element
package using test motor. |
