@article{Bianchi2007InfluenceOR, title={Influence of Rotor Geometry of an IPM Motor on Sensorless Control Feasibility}, author={N. Bianchi and S. Bolognani}, journal={IEEE Transactions on Industry Applications}, year={2007}, volume={43}, pages={87-96} }
The sensorless control technique based on the superimposition of a high-frequency stator voltage is commonly used to detect the rotor position of a synchronous interior-permanent-magnet (IPM) motor. This technique is effective at zero and low motor speed, where back electromotive force is null or extremely low. Then, the accuracy of the rotor-position detection depends strictly on the rotor saliency, that is, on the geometry of the IPM rotor. This paper aims to determine some IPM rotor-design… CONTINUE READING
