Abstract: In this paper, we propose a simulation algorithm for driving characteristics of interior permanent magnet synchronous motor (IPMSM) for electric vehicle considering nonlinear parameters like d-axis and q-axis inductances as well as core loss. D-axis and q-axis inductances as well as core loss parameter are changed according to both current magnitude and current angle between q-axis and current axis because of nonlinearity of magnetic flux density in stator and rotor core. Therefore, the calculation of d-axis and q-axis inductances with nonlinearity of magnetic flux density and core loss is performed by using FEM. We can get precise driving performance of traction motor for electric vehicle adopting nonlinear d-axis and q-axis inductance table and core loss table.

Keywords: Electric vehicle, IPMSM, driving characteristics, nonlinear inductance and core loss
