Abstract :
D- and q-axis inductance are expected to have ripple characteristics due to the difference of magnetic saturation level of each axis. In this paper, inductance variation of the interior permanent magnet synchronous motor (IPMSM) is calculated with finite element analysis, and cause of inductance variation is analyzed. Finally the validity of this paper is verified by the comparison to the experimental result
