Abstract

In the case of the interior permanent magnet synchronous motor (IPMSM), it is important to know the accurate machine parameters in the design step. In particular, d- and q- axis inductance are expected to have ripple characteristics, due to the mechanical structure and the degree of magnetic saturation. In this paper, this feature is expressed as inductance variation. Inductance variation of the IPMSM is calculated with finite element analysis, and the reason for inductance variation is identified. Finally the validity of this paper is verified by the comparison with the experimental results.
