FEETECH FT860B Servo Motor

The FT-860B-C001 is a high-speed, high-torque 7.4V 60KG-class digital servo powered by an efficient brushless motor and protected by a robust aluminum case for optimal durability. Featuring heavy-duty steel gears with a 1/356 gear ratio, dual ball bearings, and a standard 25T/5.9mm horn gear spline, it is built to handle demanding robotic applications. Operating over a 6–9V voltage range, this servo delivers a massive peak stall torque of 70kg.cm and a rated torque of 23kg.cm at 8.4V, achieved at an ultra-fast no-load speed of 0.086sec/60° (115RPM). Driven by a pulse width modulation system (500–2500 µsec) on a digital comparator, it ensures an incredibly precise 180°±5° running degree with counterclockwise rotation, a dead band width of ≤4 µsec, and no mechanical limit angles. Weighing 84±2g with a 30±0.5CM connector wire, it offers an exceptional balance of fast response, incredible strength, and structural reliability for competitive robotics and industrial automation.
