Brushless DC drive BLAR-090210-MH-MD

permanent magnetdigitalhigh-performance

Product overview
The BLAR series is an industrial high-performance intelligent digital brushless DC drive family combining positioning control and motor-drive functions in a single unit. The BLAR-090210-MH-MD is intended for speed and torque control of permanent-magnet brushless motors (Hall-sensor or sensorless) and supports system integration when supply, feedback and installation conditions are confirmed.
