Abstract

 To reduce the large errors of low order modes in modal simulation for switched reluctance motor (SRM),  an improved method for modal simulation based on static precomputation is proposed. A 3dimensional finite element model for SRM is established. The simulation research is carried with the existing simulation method and the improved simulation method. Experiments are conducted for validation. Data analysis results showed that for low order modal calculation, the existing methods still have some shortcomings. And the improved method based on static precomputation can make the relative error less than 5% by considering the effects of assembly stress and motor weight stress.

Key words：  switched reluctance motor; modal analysis; motor modeling; static precomputation
