要約(英語): In recent years, the demand for position sensorless drives in motor drives has been increasing, and various methods to implement them have been studied. For sensorless driving at a low speed, a method using a saliency PMSM has been proposed. However, applying conventional techniques is difficult for SPMSM. In this paper, we propose a low speed sensorless drive for SPMSM without saliency in general. Then, we demonstrate the principle of anisotropy of the inductance of the SPMSM generated by the d-axis current and magnetic saturation by the magnet flux.In addition, we verify that the position can be detected with an error of 15°. In addition, we show experimentally that the rated load operation can be at a low speed.
