再給電時のセンサレス永久磁石形同期電動機の制御 Sensorless PM Synchronous Motor Drives at Reclosing Electric Supply.
This paper presents sensorless PM synchronous motor drives at reclosing an electric supply. To realize the stable restarting, the initial rotor position and speed at reclosing are needed. The authors propose the current vector-based estimation algorithm of the initial position and speed when the armature is shorted by the inverter. The estimated position and speed can be calculated from the direction and amplitude of the current vector, respectively. The effectiveness of the proposed estimation algorithm is verified by experiments using a 6-pole, 1.5kW, 1500rpm test motor. The stable sensorless restarting using the estimated position and speed is achieved.
