The discontinued KO Propo PS-901 BH is a high-performance analog servo from the esteemed PS line, likely featuring a high-end Brushless motor ("B") and tuned for High-torque ("H"). This servo is an absolute powerhouse, designed for the most extreme, high-load applications in a standard-size package. It is the ultimate steering servo for a 1/8 scale truggy or a giant-scale 3D aircraft's rudder, where its immense, brushless-driven torque can handle any load with ease. The brushless motor also provides superior efficiency and a much longer lifespan than conventional motors.
The identity of the PS-901 BH is its intelligent, unstoppable, long-life power. The brushless motor can deliver its massive torque all day without overheating or fading, and its performance will not degrade over time. It is a professional tool for the expert user who needs total control over an immense amount of power, backed by the reliability of a brushless system.
In heavy-duty industrial robotics, the PS-901 BH is an unparalleled actuator. Its brushless motor's longevity is perfect for high-cycle, heavy-lifting applications on a factory floor. Its immense torque makes it suitable for the most demanding tasks, where it can provide years of maintenance-free, high-performance operation.
