The PA-R-250-9-OPV-servo is the high-power version of the well proven PA-R-250-8-OPV-servo-actuator. We implemented a high-output-brushless DC motor and adjusted the gear-train as well as the servo case design. Its power-to-weight ratio is second to none.
In conjunction with our PA-RA-3 electromagnetic OPV clutch-assembly this makes a perfect OPV-servo.
