FEETECH FT7125 Servo Motor

The FT-7125-C001 is a high-performance 7.4V 25kg-class 180-degree digital servo featuring a reliable core motor and a rugged aluminum case for optimized structural durability and thermal dissipation. Engineered for robotics, industrial automation, and advanced RC applications, it incorporates ultra-reliable steel gears with a 1/275 gear ratio, dual ball bearings, a standard 25T/5.9mm horn gear spline, and no mechanical limit angles. Supporting a flexible operating voltage range of 4–8.4V, this digital servo delivers a peak stall torque of 28.5kg.cm and a rated torque of 9.5kg.cm at 8.4V, with a no-load speed of 0.139sec/60° (58RPM). Driven by a digital comparator system with pulse width modulation (500–2500 µsec), it ensures a precise 180°±5° running degree with counterclockwise rotation, a dead band width of ≤4 µsec, and a stable stop position at 1500 µsec. Weighing 64.5±1g with a 30CM connector wire, it provides reliable torque and precise positioning for demanding motion control tasks.

Common use cases: Humanoid robot arm and shoulder joints, high-end RC car and crawler steering, UAV payload gimbal pan/tilt axis, competition robot actuators, and applications requiring 28.5kg.cm torque with wide 4–8.4V voltage compatibility.
