Digital Control of Permanent Magnet Synchronous Motors
نویسنده
چکیده
Permanent Magnet Synchronous Motor (PMSM) variable-speed drive is widely used in the industry because of its particularly high mechanical power density, simplicity and cost effectiveness. Eliminating the mechanical sensor mounted on the shaft of the motors gives further improvement. These drives are referred to as “sensorless” electrical drives. In this paper a novel sensorless algorithm is proposed for the permanent magnet synchronous motor drive with β=180° pole-width rectangular field.
