Motion Processor Gives Brushless Motors Stability In Wide Range Of Applications

Capable of improving brushless motor stability by providing sinusoidal commutation, the MC1231A motion processor performs software-based commutation to reduce torque ripple, oscillation, overshoot and audible noise levels resulting in smoother motion. It is suited to direct-drive brushless applications such as medical automation, semiconductor handling, and analytical equipment. The processor receives incremental quadrature encoder signals at the input and outputs the sinusoidally commutated motor signals appropriate for driving three- and two-phase brushless motors.
