Product overviewThe BLAR series is a general-purpose intelligent digital brushless DC drive family integrating positioning-capable control and brushless motor drive in a single unit. Series power capability reaches up to 15 kW and supports Hall-sensor or sensorless BLDC motors. The drives are intended for speed and torque control and for integration into motion systems when supply, feedback and installation conditions are defined.
