Sensorless permanent magnet synchronous motor (PMSM) drive systems have become more attractive due to their advantages, such as reduction of hardware complexity and hence the system cost and increment of system reliability. In order to correctly obtain the rotor position required for the appropriate control, various methods have been proposed. Among them, the most versatile method makes use of the structural and magnetic saturation saliencies of the PMSM. This paper presents a non-linear model of permanent magnet synchronous motors with the saliencies. The phase inductances of a PMSM motor are measured and expressed by Fourier series under different stator currents and rotor positions according to its pattern. The simulated dynamic performance is compared with that based on a model without considering saliency to verify the effectiveness of the proposed PMSM model.
