Intelligent sensorless servo

Ann Arbor, Mich.—ISS Series Intelligent brushless servo controllers use a DSP for sensorless closed-loop velocity control of three-phase PM brushless dc motors. A proprietary sensorless flux vector algorithm regulates motor speed within ±0.1% with varying loads. ISS Series comes in three initial power ratings: 7/10 A, 14/20 A, and 21/30 A (continuous peak).
