Notes
- The Blue Bird BMS-761DD is another marvel of servo technology, leveraging a non-contact magnetic encoder for positioning and a high-speed digital coreless motor. This servo is specifically tuned for applications where blistering speed is the most important attribute, but without any sacrifice in precision or longevity. It is the ultimate tail rotor servo for large 700-class and bigger helicopters. It is also a premier choice for any application where the fastest possible, highly precise response is needed. The magnetic encoder ensures that this incredible speed is paired with perfect, wear-free centering, while the coreless motor provides the instantaneous acceleration to achieve its phenomenal transit times.
- The defining characteristic of the BMS-761DD is its pursuit of ultimate, repeatable speed. Standard high-speed servos are fast, but their precision can degrade as their potentiometer wears. The BMS-761DD’s magnetic encoder solves this problem, guaranteeing that its perfect centering and high resolution will last for the life of the servo. This gives competitive helicopter pilots a huge advantage, providing a tail control system that is not only incredibly fast but also absolutely consistent over the long term. It is a servo that delivers a new level of confidence and performance.
- In the world of high-speed robotics and research, the BMS-761DD is a powerful tool. It would be ideal for controlling the guidance fins on a high-speed experimental rocket or drone. It is also an excellent choice for use in advanced haptic feedback systems, where its ability to produce very fast, precise, and repeatable movements would create a more realistic and immersive tactile experience. For any scientific or robotic application that requires sustained, high-speed, high-precision cycling, the BMS-761DD offers a level of performance and endurance that is second to none.
