Abstract :
This paper proposes a new sensorless vector control method for energy-efficient and wide-speed-range drives of permanent-magnet synchronous motors. The proposed sensorless method has the following features: 1) wide-speed-range drive under voltage limit; 2) current limitation; and 3) high efficiency. These features are realized in a very simple manner and can operate adaptively in all sensorless driving modes, including motoring/regenerating and steady/transient states. The usefulness of the proposed method is verified by extensive experiments.
