Abstract: Machine magnetic parameters influence the control performance of an interior permanent magnet (PM) machine, in both the constant torque and the flux-weakening operating regions. In this paper, the finite element model of the motor considering magnetic cross-coupling was presents, through analyzing the inductance calculation model, a more accurate model of the inductor parameters was proposed. The experiments analysed the performance of motor control under the different parameters and the influence of magnetic saturation and cross-coupling. The experimential results verify that can effectively improve the performance of motor control using the parameters proposed in this paper.
